Question

Hi!
1) How does motion change when the strength of a force acting on an object changes? How does motion change when the force changes direction?
2) How can an object be stationary, or motionless, it multiple forces are acting on it?
Thank you! :)

Answer 1

(1) When the strength of the force changes, the motion of the body is either accelerated or retarded depending upon whether the strength has been increased or decreased.

When the direction of the force changes,the motion of the body is retarded in the initial direction.

(2)If the net resultant of all the forces acting on the body is zero, then the body will be motionless.
