Witryna28 gru 2024 · Impulse ( J ) is defined as the change in total momentum p ("delta p," written ∆ p ) of an object from the established start of a problem (time t = 0) to a specified time t . Systems can have many colliding objects at a time, each with their own individual masses, velocities and momenta. However, this definition of impulse is often used to ...
