What do yo-yos and roller coasters have in common? Let's find out.
Your mission: Design a yo-yo.
Energy: The capacity to do work. In physics, work occurs when a force moves an object though a distance. Work is defined by the mathematical calculation of W = F · x. (W= work, where F is the applied force and x is the distance moved or the displacement.) Energy is classified under two major categories, potential energy and kinetic energy.
Kinetic energy: The energy possessed by a body in motion. It is calculated as one-half the mass of the body times the square of its speed.
Potential energy: Stored energy, such as the energy stored chemically in a battery, the gravitational energy due to the position of a body such as roller coaster car at the top of the drop, the energy stored in a spring, or the energy stored in molecular bonds.
