Using the concept of momentum, Newton's second law can be rewritten as , (1) where is the net force acting on the object, and is the rate at which the object's momentum is changing. If the object is observed during an interval of time between times and , then integration of both sides of equation (1) gives . (2) The right side of equation (2) is simply the change in the object's momentum . The left side is called the impulse of the net force and is denoted by . Then equation (2) can be rewritten as . This equation is known as the impulse-momentum theorem . It states that the change in an object's momentum is equal to the impulse of the net force acting on the object. In the case of a constant net force acting along the direction of motion, the impulse-momentum theorem can be written as
