right
3
If M1 is greater than M2
M1 must be moving downwards
M1 accelerates upwards
M1 must be moving upwards
M1 accelerates downwards
4
A man standing in an elevator moving with constant speed upwards...
Experiences a net force
has a dashing mustache
has zero net force acting on them
experiences greater Normal force than gravity
5
immediately AFTER hitting an air-hockey puck on a frictionless plane, it will generally ___
experience a net force
move with constant velocity
move with increasing velocity
increase its inertia
6
Compare magnitudes of normal force to gravitational force.
gravity is only greater than normal if it slides
Normal force > weight
Normal force = weight
Normal Force < Weight
