A car's speed is often determined by the friction between its wheels and the road. When you drove your toy car over the smooth tile, the wheels were met with little resistance. Try sweeping your finger against the tile --is it met with any resistance, anything that somehow stops it …

Q & A: Which ball falls fastest. Learn more physics! Great question. As it turns out, the force of gravity tries to make everything accelerate downward at EXACTLY the same rate, no matter how light or heavy it is. This means that if you dropped a basketball and a tennis ball at the same time (from the same height) they will hit the ground at ...

A: Upper string because it supports the weight of the ball in addition to your pull. The lower string supports only your pull. The upper string is more likely to break. Weight is important here. B: Bottom string; the mass of the ball (its inertia) is more important than its weight in this case.

As a person dragged the mouse over the mouse pad, the ball would roll across the surface, sending that information to the computer. Without a soft mouse pad to cause enough friction to roll the ...

Now, there are 2 forces on the object - its weight pulls down (toward the center of the Earth) and the ramp pushes upward, perpendicular to the surface of the ramp (the "normal" force). What happens is that, again, mass cancels out of Newton's Second Law, and the result is the prediction that all objects, regardless of mass or size, will slide ...

20%On what surface does a ball roll faster on. ... I would like to know different types of surfaces that would make any kind of ball roll faster. Also what would be the different variables of the ball rolling faster in the sequences. Submitted: 14 years ago. Category: Homework. Show More.

ball moves. Listen for words that describe the ball's motion (fast, slow, straight, bouncy, etc.). Help students begin to notice a pattern in how the ball moves (The ball rolls in a straight line. More force, or a harder push, makes the ball roll faster and farther.) Example: students roll ball to targets at varying distances (short, medium, long).

Answer (1 of 8): At least one speed record on bicycle is held by a rider on a bicycle with 16 in wheels. Liners 1,2,3 So the assumption that "big wheels roll faster" is not necessarily true. Especially if you have the luxury of riding on a track covered …

This means it will be going faster along the flat surface at the bottom of the hill than it did along the flat surface at the top. An object that goes up a hill will be going at a slower speed at the top than at the bottom of the hill. This is because moving up or down a hill changes one kind of energy into another.

This type of friction is called rolling friction. Rolling friction is affected by the texture of both the surface and the rolling object. Had I used a tennis ball it probably would have rolled a shorter distance because of the ball's texture. Rolling friction is also affected by how large the contact area is between the object and the surface.

Not all balls are equal. Mass and elasticity affect how high the ball will bounce, and how far it will travel. So does the friction of the surface on which the ball lands. This lesson compares the bouncing of a bocce ball, a tennis ball, and a golf ball. Even a hard rubber ball won't bounce, if you drop it onto the dry part of a sandy beach.

The same principles apply to spheres as well—a solid sphere, such as a marble, should roll faster than a hollow sphere, such as an air-filled ball, regardless of …

The steeper the ramp the faster it speeds up. (If this doesn't make sense, imagine a ball rolling down a board. If the board is almost straight up and down, then the ball is basically falling, so it's speeding up really quickly. But if the board is almost flat with the ground, it will take a lot longer for the ball to roll down it.)

Normally a ball rolls faster on dirt than grass. it also depends on the size of ball, speed at which it is realesed, surface of the dirt (for example if dust particles are bigger then there is more resistance, … that would be cement … its smoother … » More detailed Does a ball roll farther on grass or dirt – Wiki Answers

Procedure. Step 1: You will need to get a ball. Step 2: You will need to get a carpet. Step 3: You will roll the ball on the carpet. Step 4: You can go to a park and roll the same ball but on the dirt. Step 5:You will do the same thing that you did in the others,but you will do it on the grass. Step 6:You will need to measure the distance the ...

$begingroup$ In regard to Chris2807's answer, I have a question: If a ball is rolling down the hill on its own, there is a continual component of gravitational force that pulls it down the incline. Since this force produces no torque about the center of mass, I have concluded that a frictional force must be exerted on the contact point at all times when the ball slides down the incline, or ...

Does A Ball Roll Faster On A Smooth Surface Or On A Rough Surfaces? Physics Assuming the smooth surface is flat and level, based upon equations involving rates and time a smooth... A Ping Pong Ball With A Mass Of 2.20 Grams Rolls Along A Frictionless Table With A Velocity Of 0.850 M/s. What Is The Momentum Of The Ping Pong Ball? Algebra

What does roll on expression mean? Definitions by the largest Idiom Dictionary. Roll on - Idioms by The Free Dictionary ... To apply on (a surface) in a rolling motion or by using something that rolls. In this usage, a noun or pronoun can be used between "roll" and "on." ... The days just seem to roll on faster and faster lately.

2. Divide this number into 40.91 (i.e. 40.91/2.52 = 16.23 mph). Ball Track - The portion of the bowling ball, which comes in contact with the lane as it rolls down the lane. Bifilar - The use of two cords or wires to support the test cradle in testing the radius of gyration of a bowling pin.

Bill Hall. Be sure that ball speed is really what you need. The surface of the ball, the volume of oil on the lane, and the lane surface all can affect ball speed. The first thing you need to do is to make sure that you have a rhythm that can help you generate the speed you want. A common mistake is that bowlers will put the ball into the swing ...

This ball hooks noticeably earlier than the one at 4,000 and will not hold the pocket. After making an adjustment of five boards with the bowler's feet, the 1,000-grit ball now will hold the line to the pocket. Surface is the biggest influence on your ball's reaction. Surface dictates about 70 percent of the total ball motion.

New ball bearings developed by Coo Space solve that problem in an ingenious new way. Instead of forcing balls apart with a cage or retainer, Coo Space puts small divots in the track the balls roll ...

Assume the objects roll down the ramp without slipping. The sphere The ring The disk Three-way tie Can't tell - it depends on mass and/or radius. We can take the winner of this race, if there is one, and race it against a slippery block that slides down the ramp with negligible friction and see which one wins that race.

The Ball Screw requires a minimal starting torque due to its rolling motion, and does not cause a slip, which is inevitable with a sliding motion. Therefore, it is capable of an accurate micro feeding. Fig.4 shows a travel distance of the Ball Screw in one-pulse, 0.1-μm feeding. (LM Guide is used for the guide surface.)

The reason the ball rolled the fasted over the timber surace, was because there was nothing to stop it from rolling. The tiles have dented lines in between them, which is the reason the ball may have slowed down. The carpet exerted more friction then both the other surfaces, and the friction caused the slowing down of the ball. Method

The angle of the slope is θ, and mass of one of the ball is m, and its radius is R. a = α R where α is the angular acceleration of the ball, and torque by static friction f is τ = f R, and m g sin. ⁡. θ − f = m a. we also know τ = β m R 2 α where β is some constant (depends only on the distribution of mass). Solving for a yields a ...

When taking a lay-up from short range, players are taught to let the ball roll off their hands toward the rim (as you can see in the game …

3. The more you practice writing faster it trains your muscle memory and helps you to become a faster writer. 4. Use the right type of pen if you are writing with a pen that is scratchy and not smooth writing then this will slow you down. 5. Cheap paper that has a rough surface will also affect your writing speed.

To analyze rolling without slipping, we first derive the linear variables of velocity and acceleration of the center of mass of the wheel in terms of the angular variables that describe the wheel's motion. The situation is shown in (Figure). Figure 11.3 (a) A wheel is pulled across a horizontal surface by a force →F. → F.
