Question

What is the difference between variable force and constant force?

Answer 1

  If the force acted on a body is varied (changed with time) then the force is said to be variable force.
If a variable force is acted on a body, the motion of the body is non-uniformly accelerated.
 
If the force acted on a body is not varied with time (i.e., the same amount of force) then the force is said to be Constant force.
 
If a Constant force is acted on a body, the motion of the body is uniformly accelerated.
