Energy is the ability to do work or cause a change
in direction, speed, shape or
temperature of an object.
All energy can be grouped into:
Potential
Defined as the energy
the matter of an object
has. (stored energy)
Kinetic
Defined as the energy of
a moving object.
Potential:While work is waiting to be done, when there is potential for work to be performed, we call it potential energy.
An object can store energy:
By lifting it up: Gravitational Potential Energy
By stretching or squashing it: Elastic Potential Energy
An object can increase its potential energy:
Increase the object’s weight.
Increase the height an object is raised to.
Kinetic Energy is the energy of motion (movement).
When work is actually being done we call it
kinetic energy.
Moving objects have energy:
Kinetic Energy is measured by how much work is done
to change an object’s motion.
Mass and velocity both affect kinetic energy.
Higher Velocity = Higher Kinetic Energy
