# Which Surface Allows A Ball To Roll The Fastest?

## How do you slow down a rolling object?

Friction is a force that slows down moving objects.

If you roll a ball across a shaggy rug, you can see that there are lumps and bumps in the rug that make the ball slow down.

The rubbing, or friction, between the ball and the rug is what makes the ball stop rolling..

## What force causes a ball to roll?

frictionThe ball rolls because: the friction present between the surface pushes the atoms/particles in contact with surface or ground backwards, hence with centre of mass moving in a direction, the ball’s bottom surface(ie. The surface in contact) moves in opposite direction or backwards, causing the ball to roll.

## Which ball will roll the farthest?

Conclusions. The heavier balls (bell ball and small bouncy ball)l do not roll as far. The big playground ball is light and rolls the farthest.

## Does the surface of the ground affect how far a ball will roll?

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. … Conclusion: The marble rolled farther on smoother textures, with texture clearly affecting the distance traveled.

## What force slows down a rolling ball?

friction forceA ball rolling on a horizontal surface slows down as it rolls, due to rolling friction. The friction force is due to static friction so no net work is done by that force, and it does not act to dissipate energy.

## Does an object travel farther on a smooth or slippery surface or on a rough surface?

Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. Heavier objects also have more friction because they press together with greater force. Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy.

## Does a heavier ball fall faster than a lighter ball?

Acceleration of Falling Objects Heavier things have a greater gravitational force AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.

## Do heavier objects slide faster?

The force of gravity is the weight of the body. … Hence an object with greater mass feels greater force than the other one. So even if the slope is same for both objects, a massive object moves faster through the slope than a less mass object.

## How does the length of a ramp affect speed?

So the ramp increases, the velocity will also increase. If you also decrease the height or a ramp your velocity will decrease as well as your speed. … ENERGY- energy is how much speed is going into the object.

## Does surface affect speed?

The model car went fastest down the surfaces with the least amount of friction and went slowest down the surfaces that had the most amount of friction. I found that the order of surfaces from shortest time to longest time was bare wood, Styrofoam, 120 grit sandpaper, 80 grit sandpaper, and 50 grit sandpaper.

## Why is rolling a ball down a hill considered an unbalanced force?

Terms in this set (25) -An object at rest will remain at rest and an object in motion will remain in motion until an unbalanced force acts upon them. (Ex~A ball will roll down a hill, but will eventually stop because of friction.) … -Gravity acts on objects at rest.

## What does a balanced force mean?

When two forces acting on an object are equal in size but act in opposite directions, we say that they are balanced forces . … a stationary object stays still. a moving object continues to move at the same speed and in the same direction.

## Can a balanced force be moving?

Balanced forces do not change the motion of an object. The motion of an object will not change if the forces pushing or pulling the object are balanced. An object that is sitting still will stay still if the forces acting on it are balanced.

## Does a heavier ball roll faster than a lighter ball?

After a two sample t-test, we find that heavier rolling objects have a statistically faster clear time for a given inclined plane in comparison to lighter rolling objects. In addition, heavier objects will be more resistant to the effects of air resistance and rolling resistance.

## Why does a ball rolling on ground stop on its own?

For example, when the ball rolls on the ground, the force of friction acts between the surface of the ball and the surface of the ground. The irregularities between the two surfaces lock into each other and thus, stop the ball from moving any further unless it is moved by an external force.

## Can a ball roll forever?

It cannot accelerate the body, for it has no component in either direction that the body could move. So we conclude that there’s no force that can change the horizontal motion of the body, and no torque to change its rotation, so therefore if it’s rolling, it will roll forever without deceleration.

## What is an unbalanced force example?

If you kick a football and it moves from one place to another, it means that unbalanced forces are acting upon it. Ball moves from one place to another after kicking it. This is an example of unbalanced force.

## Does friction affect the distance the ball will travel?

The greater the air pressure in the ball, the farther it will travel when a force is applied. … The student will learn about the relationship between air pressure and friction: the lower the friction, the farther the ball will go.

## What stops a ball from rolling?

When you roll a ball on the ground, the electrons in the atoms on the surface of the ground push against the electrons in the atoms on the surface of your ball that is touching the ground. A rolling ball stops because the surface on which it rolls resists its motion. A rolling ball stops because of friction.

## Why does a ball eventually stop bouncing?

If you drop the basketball, the force of gravity pulls it down, and as the ball falls, its potential energy is converted to kinetic energy. … This is because the basketball had an inelastic collision with the ground. After a few bounces, it stops bouncing completely.

## On which surface a ball rolled with same force will travel more distance?

Since the the coefficient of friction is more in case of the ground made up of concrete than a marble floor hence the ball will cover mode distance in case of a marble floor.
