Energy Notes 6 th Grade Science

Chapter 5 Section 1 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.

Chapter 5 Section 2 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

Chapter 5 Section 3 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.
