How does momentum and inertia apply to ping pong

I need two more examples for each...
For momentum I have: A moving ping pong ball has little momentum which makes it easy for players to stop the ball.

And for Interia I have: The ball will keep bouncing until the paddle hits it again in the opposite direction.

I need help coming up with two more examples for each, it can be about the players movements too.... I just need help :| Thanks.

Momentum is "The quantity of motion of a moving body, measured as a product of its mass and velocity."
Scientists calculate momentum by multiplying the mass of the object by the velocity of the object. It is an indication of how hard it would be to stop the object. If you were running, you might have a mass of 50 kilograms and a velocity of 10 meters per second west (really fast). Your momentum would be 500 kg-m/sec west. So in your case, you get the mass of the ping pong ball (You can find it by using a triple-beam balance or Mass=Density x Volume) and see how fast the ball of the ping pong travels. So you would multiply the mass of the ping pong (m) by its traveling speed (s) -> mass*speed=Momentum.

Inertia is "A property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force"
So, inertia would apply to a ping pong when the ball is resting on a surface ( resting state) and an acting force ( the paddle) changes the speed or direction. Keep in mind that other forces such as gravity will affect the motion. Another example of the effect of inertia on a ping pong is when it is in its active state or when a person hits the ball with the paddle. When a second player (external force) hits the ping pong ball, it changed not only the direction but also the speed at which the ping ping ball is traveling.

I hope this helped and good luck!

for momentum, billiards and in bus wherein 2 bus in different mass will have different momentum. but for billiards of course, though the balls have the same mass, the linear momentum is still the same.

for inertia, a passenger on a moving train. the passenger will keep moving in line with the direction of the train even the train suddenly decrease in speed.

The bat your using has momentum
Inertia: doesn't that really apply to the balls reluctance to be moved? The balls reluctane to change shape upon impact (though it will)
