WebIn equation form, linear momentum p is. p = m v. You can see from the equation that momentum is directly proportional to the object’s mass ( m) and velocity ( v ). Therefore, the greater an object’s mass or the greater … Web2 jan. 2024 · However, to answer your question, momentum ( p) is equal to the product of the mass ( m) of an object and its velocity ( v ). Thus, p = m v ⇒ v = p m. This may then be put into the first equation, such that, KE = 1 2 m v 2 = 1 2 m ( p m) 2. Thus, KE = 1 2 m p 2 m 2 = 1 2 p 2 m. Which, using your eV notation, would then imply that,
