1- Apply the following forces:

BLUE object:  F = 10 N, GREEN object: F = 10 N.

BLUE object:  F = 5  N, GREEN object: F = 10 N.

BLUE object:  F = 3 N,  GREEN object: F = 10 N.

Note that the forces are in the same

direction as the displacement.

How does work change in relation to the applied force?
    Are they proportional, are they inversely proportional, constant, etc.?

2- Change the displacement:

BLUE object:   F = 10 N, d = 5 m.

GREEN object: F = 10 N,  d = 2.5 m.

BLUE object:  F = 5 N,  d = 5 m.

GREEN object: F = 10 N, d =  1 m.

How does work change in relation to displacement?
