ENERGY, MOTION, FORCE, WORK
True or False
Is air a form of energy?
False
It is the energy that an object possesses by virtue of being in motion.
Kinetic energy
Energy that results from the position or shape of an object is called ____________ energy.
Potential
It is the energy an object has due to its motion, shape, position or combination of these factors.
Mechanical Energy
It occurs when one form of energy changes into another.
Energy Transformation
An object is in _______ if its position is relative to its surroundings
motion
Factors affecting Kinetic Energy
speed and mass
Two types of Potential Energy
Gravitational and Elastic
A type of potential energy stored in the nucleus.
Nuclear Energy
It takes place when energy moves from one object to another.
Energy Transfer
It is the ability to do work or cause change.
Energy
True or False:
