The kinetic energy is zero at the start because the object is initially at rest. Since kinetic energy is given by 1/2 mv², and the initial velocity (v) is zero, the kinetic energy is also zero.

The kinetic energy is zero at the start because the object is initially at rest. Since kinetic energy is given by 1/2 mv², and the initial velocity (v) is zero, the kinetic energy is also zero.
At the start of its fall, the object’s kinetic energy is zero because its initial velocity is zero. All of its mechanical energy is in the form of gravitational potential energy, which then transforms into kinetic energy as it falls.
