Why does a ball move in a straight line rolling on a table but follows a curved path once it rolls off?
The curved path is the result of gravity and inertia acting on the ball. As it leaves the table gravity pulls it to the ground at an increasing rate while inertia keeps it moving in its original direction. The table prevents the rolling ball from falling thus negating that curvature caused by gravity, and making it follow a straight line.
When a ball is at rest all the forces acting on it are?
Equal.
Which material caused the forces acting on the straw and clay ball to change?
salt
What forces act on a rolling ball?
It acts as a rolling friction or rolling resistance when it starts to roll on a flat surface , it resists the direction of rotation of the object in both clock wise and anti clock wise direction.
Is a ball rolling in a straight line at a constant speed in equilibrium?
Yes. Because it is moving at a constant speed, we know that it is not accelerating (changing its speed). This means that all forces acting on it are balancing each other, so the net force is 0.

What form of energy did the table tennis ball have when it was rolling?
Rolling (motion) is an example of Kinetic Energy.

Equal.
A rolling ball will eventually stop rolling why does it do that?
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).
Why the momentum of a billiard ball rolling on a billiard table change?
Friction between the ball and cloth.
Why does momentum of a billiard ball rolling on a billiard table change?
Friction between the ball and cloth.
When a ball is at restall the forces acting on it are?
Either there are none, or if there are any, then the whole group of forces is balanced.
Is friction acting on a body which is in pure rolling?
yes there is still alittle friction on a ball that is in pure rolling because there is still interaction between the atoms that contact the surface of the ball and the floor

What are the different forces acting on the ball while it’s in the air?
Gravity, force, and acceleration.
How do you find the net force in each axis on a rolling ball?
Generally, only two forces act on a rolling ball. Gravity and friction (there has to be friction because without it, the ball would just slide). These are pointed directly in the x and y directions. If the ball is rolling down a slope, you can use trigonometry to find the force components.
