Newton’s cradle

Jun 10, 2020 | Mechanics | 0 comments

Newton’s cradle is a device that demonstrates conservation of momentum and energy using a series of swinging spheres. When one sphere at the end is lifted and released, it strikes the stationary spheres, transmitting a force through the stationary spheres that pushes the last sphere upward.
The marbles hurtling down curved inclined channels demonstrate these conservation principles, too.
Find out which reaches faster – a marble down the straight inclined channel or the one down the curved channel.
Also, why the roller in double conical shape apparently defies gravity and rolls up the inclined rods.

Wave motion & Resonance

Wave can be described as a disturbance that travels through a medium, transporting energy from one location (its source) to another location without transporting matter. There are two basic types of wave motion for mechanical waves: longitudinal waves and transverse...

Pendulums & SHM

The motion of a simple pendulum is very close to Simple Harmonic Motion (SHM). SHM results whenever a restoring force is proportional to the displacement, a relationship often known as Hooke's Law when applied to springs. Where F is the restoring force, k is the...
