What is the relationship between kinetic and potential energy?
Work The use of force to move an object over a distance. Formula: Force (N) x Distance (m) Formula: W=Fd
Energy The ability to do work or cause a change.
Potential Energy The stored energy that an object has due to its position, molecular arrangement, or chemical composition.
Kinetic Energy The energy of motion.
Gravity The force that pulls objects toward Earth’s surface. The force that objects exert on each other because of their masses.
Elastic Potential Energy Potential energy stored as a result of deformation of an elastic object, such as the stretching of a spring or a rubber band.
Gravitational Potential Energy Potential energy stored due to gravitational pull. Formula: GPE= weight (N) x height (m) GPE= mass x 9.8 m/s 2 x height GPE=mgh The unit for GPE is the joule.
Gravitational Acceleration Acceleration due to the pull of gravity. (9.8 m/s 2 )
Joules The unit used to measure energy and work. *One joule of work is done when a force of one newton moves an object one meter.
Newtons The SI unit for force. (N) *This is also the unit for weight.
Momentum A measure of mass in motion. Formula: mass x velocity p=mv
Velocity Speed in a specific direction. -Speed is a measure of how fast something moves through a particular distance over a definite time period. Formula: Speed = distance/time
What is energy? Energy measures the ability for things to change themselves or to cause change in other things. A joule (J) is the S.I. unit of measurement.
Energy and Its Conservation. Introduction Energy is always present, but never visible! Instead, we see the evidence of energy: movement, sound, heat,
THE NATURE OF ENERGY IPC Notes. ENERGY Energy is involved in every change that occurs Energy can be found in many different forms ex) thermal, electrical,

Chapter 5 Section 1 Every change that occurs requires energy. Energy is the ability to do work. All moving objects have energy You can tell an.
ENERGY The stuff that makes things go.. What is Energy? - Energy = The ability to do work or cause a change in motion. -Measured in Joules (J) & calories.
Energy! We have both types of energy: Kinetic and Potential.
Ms. Moore 10/1/12. Energy is required for any change that occurs, no matter how small. Energy is the ability to cause change. Examples: Forms.
