kinetic+energy

Definiton-the mechanical energy that a body has by virtue of its motion

5 Detailed facts
 * When an object is in motion, kinetic energy is the extra energy the object uses.
 * Kinetic energy stays the same, unless the speed is changed.
 * Vibrational, rotational, and translational are all types of kinetic energy.
 * The word "kinetic" comes from the greek word "kivnan" meaning motion.
 * A spacecraft uses chemical energy, then turns into kinetic energy.

Formula: 1/2xMxV^(2) M=mass of the object V=Speed of the object

Find the kinetic energy of a 400 kg roller coaster, that is moving with a speed of 19 m/s? 19^(2) x 400 divided by 2=72200.

Find the kinetic energy of a 25 kg person, with a speed of 5 m/s? 5^(2) x 25 divided by 2=312.5.
