More realistically, Δ p is the sum of a series of small steps, such that In order to perform the integral, it is necessary to know r at all times so that F may be known at all times. A change of momentum produced by an impulse, equivalent to the average value of the force multiplied by the time during which it acts. His final momentum is therefore zero. Impulse definition, the influence of a particular feeling, mental state, etc. 3. nerve impulse. After lunch she decided, on impulse, to take a bath. The impulse experienced by the object equals the change in momentum of the object. Learn what momentum and impulse are, as well as how they are related to force. Here’s the equation: Impulse = F t. Here’s an example of impulse in action: You’re playing pool, and you strike a pool ball with the cue. Impulse = change in momentum = force × time Conservation of Momentum When there is a collision between two objects, Newton's Third Law states that the force on one of the bodies is equal and opposite to the force on the other body.
