The physics of a bouncing ball concerns the physical behaviour of bouncing balls, particularly its motion before, during, and after impact against the surface of another body. Several aspects of a bouncing ball's behaviour serve as an introduction to mechanics in high school or undergraduate level physics courses.
Floating droplets on a vibrating bath were first described in writing by Jearl Walker in a 1978 article in Scientific American. [13]In 2005, Yves Couder and his lab were the first to systematically study the dynamics of bouncing droplets and discovered most of the quantum mechanical analogs.
A bouncing ball captured with a stroboscopic flash at 25 images per second: Ignoring air resistance, the square root of the ratio of the height of one bounce to that of the preceding bounce gives the coefficient of restitution for the ball/surface impact. In physics, the coefficient of restitution (COR, also denoted by e), can be thought of as ...

A bouncing ball captured with a stroboscopic flash at 25 images per second. Each impact of the ball is inelastic, meaning that energy dissipates at each bounce. Ignoring air resistance, the square root of the ratio of the height of one bounce to that of the preceding bounce gives the coefficient of restitution for the ball/surface impact.
Bouncing ball in a rotating space station: The objective reality of the ball bouncing off the outer hull is confirmed both by a rotating and by a non-rotating observer, hence the rotation of the space station is an "absolute", objective fact regardless of the chosen frame of reference.
Newton's cradle simulation with two balls of equal mass; assuming perfect elasticity which implies no energy loss in collisions. The left ball is pulled away which lifts it, and then let go. The left ball swings back as it falls and strikes the right ball, transferring all its momentum to the right ball because they are the same mass.
The two sciences were the science of motion, which became the foundation-stone of physics, and the science of materials and construction, an important contribution to engineering. Galileo arrived at his hypothesis by a famous thought experiment outlined in his book On Motion. [14] He writes: Salviati. If then we take two bodies whose natural ...
