Question
Rank the below cases by the amount of gravitational force acting on the crate (all cases involve pushing the same crate in a straight path across level ground).
Pushing a crate at a constant 5 m/s.
Pushing a crate that is at rest, but just about to break loose and start moving.
Pushing a crate at a constant 3 m/s.
Pushing a crate at 5 m/s, but slowing down.
Pushing a crate at a constant 1 m/s.

Explanation / Answer
As gravitational force acts vertically downwards, and the crate in all the given cases is at same horizontal level, in all cases crate experiences same amount of gravitational force.
Hence gravitational force is equal in all the given cases.
A =B=C=D=E
