Consider a ball thrown straight up in the air. At what position is its kinetic energy a maximum?
Kinetic energy is the energy that possesses a body due to its motion. Its formula is
Ke = 1/2 mv²
Then, the kinetic energy is maximum when the velocity is the highest, and this is at the point where it is thrown, after this point, the velocity will be diminished and at the highest point will be equal to zero.
