Con Physics After Break Review Part 2

Finish the force interaction statement:
hand hits wall...

• hand is stopped
• wall is moved
• wall hits hand

Finish the force interaction statement:
earth pulls down on skydiver...

• skydiver pulls up on earth
• skydiver falls
• earth rises

momentum is often called...

• inertia in motion!
• :-)

the equation for inertia is

• p=ma
• p=mv
• p=mr
• p=md

an ____ is required to cause a change in momentum

• impulse
• import
• acceleration
• explosion

impulse is

• Fd
• ϑ
• FΔt
• mg

the recoil of a canon is an example of 

• conservation of momentum
• Galileo's Law
• conservation of mass
• relativity

when two objects interact momentum is conserved...
if the objects deform each other, doing work the collision is...

• elastic
• inelastic

when two objects interact momentum is conserved...
if the objects bounce off each other conserving mechanical energy the collision is...

• elastic
• inelastic

when a force acts on an object causing motion in the same direction

• work
• energy
• momentum
• inertia
