Question

Name the forces (types of forces) when their resultant force acting on a body is not zero

Answer 1

A stationary object remains stationary if the sum of the forces acting upon it - resultant force - is zero. A moving object with a zero resultant force keeps moving at the same speed and in the same direction.

If the resultant force acting on an object is not zero, a stationary object begins to accelerate in the same direction as the force. A moving object speeds up, slows down or changes direction.

Acceleration depends on the force applied to an object and the object’s mass.
Types are zaero and non zero
