Energy Notes
6th Grade Science
Chapter 5Section 1
What is energy?
What is energy?
Energy is the ability to do work or cause change
There are two basic kinds of energy: kinetic energy and potential energy.
Kinetic energy - energy that an object has due to its motion
The kinetic energy of an object depends on both its mass and velocity.
Greater MASS = Greater Kinetic Energy
Greater VELOCITY = Greater Kinetic Energy
25 mph 60 mph

Potential energy - stored energy that results from the position or shape of an object
This type of energy has the potential to do work.
Potential Energy
Types of Potential Energy: • Gravitational Potential
Energy• Elastic Potential
Energy
Potential energy related to an object’s height is called gravitational potential energy.
Potential energy associated with objects that can be stretched or compressed is called elastic potential energy.

Forms of Energy
Mechanical Energy - form of energy associated with the position and motion of an object
Mechanical Energy = Potential Energy + Kinetic Energy
Thermal Energy – total potential and kinetic energy of the particles in an object
Electrical Energy – energy of electric charges
Chemical Energy – potential energy stored in the chemical bonds that hold chemical compound together
Nuclear Energy – potential energy stored in the nucleus of an atom
Electromagnetic Energy – energy of light and other forms of radiation

Energy Transformations
and Conservation
Most forms of energy can be transformed into other forms.
Energy Transformation – a change from one form of energy to another
The Law of Conservation of Energy - states that energy cannot be created or destroyed
So where does the energy go?
Ex: A speeding car slams on the breaks.
Ex: A glass falls off the counter and breaks.
