![]() ![]() ![]() The change in momentum of a body due to the force acting on it is called impulse. What is Impulse?Ĭan you figure out when a force acts on a body for a small duration, how much will the force change the momentum of the body? That is an impulse! It is the measure of this change in the momentum of an object. So, how does momentum relate to impulse? The following section explains the relationship between the two. The formula of momentum can also be written as follows: If a bowling ball and ping pong ball have the same velocity, which one would have a greater momentum? So, increasing either will increase the momentum. Also, momentum is directly proportional to mass and velocity. So, an object at rest has zero momentum. Since velocity is involved in the calculation of momentum, it is a vector quantity. Where m is the mass in kg and v is the velocity in m/s. It is the product of mass and velocity, given by the following formula: To understand the impulse, you need to know what momentum is. Learn what is impulse, the formula for calculations, equations, examples and applications. The following article explores this important Physics concept in detail. So, The concept involves a change in the object’s momentum when force is introduced for a specific time. You use the concept of impulse in your everyday life without even realising it, for instance, when you hit a punching bag or kick a ball.
