Picture of the day
A
bouncing ball
captured with a
stroboscopic
flash
. As the ball falls freely under the influence of
gravity
, it
accelerates
downward, its initial
potential energy
converting into
kinetic energy
. On impact with a hard surface the ball deforms, converting the kinetic energy into
elastic potential energy
. Each impact of the ball is a partially
inelastic collision
, meaning that energy is lost at each bounce.
