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/s2 x height GPE=mgh
The unit for GPE is the joule.
Gravitational Acceleration
Acceleration due to the pull of gravity.
(9.8 m/s2)
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
