WebApr 16, 2024 · This ability is what we mean when we refer to an object's kinetic energy: the ability to change another object's motion or position simply by colliding with it. The equation of an object's kinetic energy depends on its mass and velocity: KE = 1 2 mv2. The kinetic energy of a moving object is directly proportional to its mass and directly ... Web4 years ago. Actually both the formula's still produce the same answer, since the initial velocity is 0. When the initial velocity is 0 then the displacement=final velocity. Initial velocity = 0. Final velocity = 2 km/h. Total time = 2 h. Avg velocity = Iv + Fv/2. Avg velocity = 0+2/2. Avg velocity = 1 km/h.
