When acted on by unbalanced forces, a stationary object accelerates in the direction of the resultant force applied, following Newton's second law.
When an object that is initially at rest is acted on by unbalanced forces, it will start to accelerate in the direction of the resultant force applied to it. This acceleration is directly proportional to the magnitude of the unbalanced force and inversely proportional to the mass of the object, following Newton's second law, ΣF = ma.
For example, if a car is at rest and a net force is applied in the forward direction, the car will accelerate in that direction until another force stops it or changes its motion. This shows how unbalanced forces can cause a stationary object to start moving.
Understanding unbalanced forces is crucial in explaining changes in an object's motion from rest to motion or from one motion state to another.
