### Mr. Scanlan work, energy and power

What is done on an object when a force causes a displacement of the object? Work
The energy of an object that is due to the object’s motion is called what? Kinetic Energy
This variable depends on speed and mass. Kinetic energy
1/2 the mass x velocity (squared) equals what? Kinetic Energy
The energy associated with an object because of the position, shape, or condition of the object is called what? Potential Energy
The potential energy stored in the gravitational fields of interacting bodies is called what? Gravitational Potential Energy
This variable depends on height from a zero level. Gravitational Potential Energy
This is the energy available for use when a deformed elastic object returns to its original configuration. Elastic Potential Energy
The symbol k, a parameter that measures the spring’s resistance to being compressed or stretched is called what? Spring Constant
The sum of kinetic energy and all forms of potential energy associated with an object or group of objects is called what? Mechanical Energy
This a quantity that measures the rate at which work is done or energy is transformed. Power
work ÷ time interval Power
force x speed Power
Mass x gravitational pull x height Gravitational Potential Energy
1/2 spring constant (K) times distance (X) squared Elastic Potential Energy
