What happens when a ball rolls uphill?
its motion and accelaration are in opposite directions
A basketball rolling across a flat floor has energy?
A basketball rolling across a flat floor has translational and rotational kinetic energy. There's a force of gravity pulling the ball down towards the floor, and a reaction force pushing the ball up away from the floor.
Why does a ball come to stop when it is rolled across the floor?
Because of the forces that act on the ball in the direction opposite to its motion ... air resistance and friction with the floor.
If you roll a ball across the floor you put the ball in motion but after time the ball stops. Does this violate Newton's first law?
No. (Friction is a force.)
The velocity time graph of a ball moving on surface of floor is shown in figure calculate the force acting on ball if mass of floor is 20gram?
a ball rolled across a horizontal table moved at cont ant velocity why?
Why does a ball come to stop when it rolls across a floor?
Friction
What's that big ball that rolls across an empty abandoned room called?
A wrecking ball.

If a ball rolls foul then hits right corner of 1st base then rolls in after 1st base is it fair or foul?
As soon as the ball touches first base, it is a fair ball, regardless of what happens after that.
What kind of simple machine is a ballpen?
It is a wheel. The ball rolls across the surface, instead of scraping across as a pencil or nib pen would.

What is the main form of energy of a ball moving across the floor?
kinetic energy
Is there a thing called rolling foul in baseball?
Yea. It usually happens if a player bunts the ball and the ball rolls foul after being bunted.

A basketball rolls to a stop along a gym floor without anyone touching it why did this occur?
The ball rolled to a stop because the opposing force of friction stopped the ball. If the floor had been frictionless, it would have continued without stopping or even slowing.
