Detailed Solution

The above statement is true.
A force can change the speed of a moving body. The action of a force can cause an object to move or speed up, slow down, stop, or change direction. A force can move a stationary object only when the applied force is greater than the resistance force acting on the object. So, if the resistance force exceeds the applied force, the object will not move. Alternatively, the object will move if the resistance force is less than the applied force. When the resultant force acting on a body is not zero, we can say an unbalanced force acts on it. When a net or an unbalanced force acts on a body, it changes its state of rest or uniform motion. Alternatively, we can say the body will move.
