Momentum and Collisions

Front

Newton's 3rd Law: When a student on a skateboarder applies a force of 20 Newton to 'push' the ball in a positive direction, what does the student experience?

Back

A negative (-) force of equal magnitude

Front

Newton's 3rd Law: When a student (40 kg) on a skateboard applies a force to accelerate a medicine ball (5kg) to the right, what force acts on the student?

Back

Exactly the same force applied to the ball

Front

The momentum of an object depends upon the object's ___________&_____________.

Back

mass and velocity

Front

You have THREE different objects with different masses traveling at different velocities. Which has the greatest momentum? Object A: really massive traveling slowly Object B: low mass traveling really fast Object C: a medium mass traveling at a medium speed

Back

We cannot say which one has the most momentum without knowing the mass and velocity
