Contact forces and collisions unit test

what happens when two object hit eachother?

when two objects collide both objects can change shape. they can also bounce back or they stick together

what causes the changes in motion and the changes in shape in a collision?

the energy and force of impact

do all objects change in shape or bend during a collision?

all solid objects do bend or change in shape when pushed in a collision

how much do you have to push on any object to deform it temporarily or permanently?

10 neutrons

how does changing speed and mass affect the force in a collision?

• it always depends on which object is being pushed and pulled

How do other contact forces from interactions with the air and the track cause energy transfers in the launcher system?

by using air resistance

collision

one object moving and one not, the other one moving and the other one not, both objects moving….. a collision is energy being transferred between 2 objects by force

force

a push or pull that can change the shape or motion of and object
