Newton’s Second Law

Unbalanced forces

When the forces acting on an object do not balance, the resultant force will cause the object to accelerate in the direction of the resultant force.

In other words, a resultant force on a body will cause it to change its velocity. This simply means that unbalanced forces will cause:

acceleration

deceleration

change in direction
