the friction and the motion of the ball both combined
Friction between the ball and the ground.
Friction. Friction.
Stop the ball
Rolling friction causes a car to stop.
the inertia
It is an example of inertia.
Any amount of force can stop either kind of ball. But a greater force is required to stop a bowling ball than to stop a soccer ball IN THE SAME TIME, because the bowling ball has more mass, and therefore more momentum and more kinetic energy.
Stop the ball
It will not, unless it is acted upon another force. If it's rolling on something, then friction will stop it (the ball rubbing on the table slows it down).
Rolling friction causes a car to stop.
the inertia
It is an example of inertia.
put your hand there to stop it.
Rolling the ball would be work and stopping the ball would be force.
Any amount of force can stop either kind of ball. But a greater force is required to stop a bowling ball than to stop a soccer ball IN THE SAME TIME, because the bowling ball has more mass, and therefore more momentum and more kinetic energy.
That force is called an Opposing Force.
Friction
Friction - between the surface of the ball, and the ground.
It is an example of momentum (sometimes called "inertia"). Velocity x mass. The bowling ball is much, much heavier. With both rolling at the same speed, the bowling ball is harder to stop because it has much more mass.
