Day 2: Potential and Kinetic Energy. What is Energy? Anything that can cause a change in matter.

 Is the ability to cause changes in matter.  Energy can transform, or change, from one form into another.  Energy is never used up.

Kinetic and Potential Energy have many forms. 1. Mechanical Energy - Energy associated with motion or position.

Energy Transfer & Transformations How does energy impact the motion of an object?

TYPES OF ENERGY by:Mckezie Mccool. ENERGY Energy is the ability to do work.

Energy: Machines, Motion and Light Energy exists in many different states. Energy can be transformed from one state to another in order to power machines.

Presentation transcript:

OA2.1 Understand energy and its conservation Potential , Kinetic, Mechanical, Electrical and Sound energy

Mechanical

Definition Word 1. Energy The ability to do work Energy causes things around us to happen

Definition Word 2. Potential energy Energy that is stored in matter. Batteries has potential energy

Definition Word 3. Kinetic energy Energy that comes from movement An object moving has kinetic energy

Potential energy Kinetic energy

NOT MOVING MOVING MOVING

Where would Potential energy be in this diagram Where would Potential energy be in this diagram? Where would Kinetic energy be?

Where would Potential energy be in this diagram? Where would Kinetic energy be?

Where would Potential energy be in this diagram? Where would Kinetic energy be? Potential energy (he is NOT moving) Kinetic energy (he IS moving)

Definition Word Mechanical Energy from moving parts energy of a machine Engine has mechanical energy to make a car move! Gears have mechanical energy to make dials on a watch move!

Definition Word Electrical energy Energy that comes from electrons moving in a substance Electrons have a negative charge!

Definition Word 6. Sound Energy from produced by sound vibrations Caused by vibrations Sound needs matter to travel through – there would be no sound in outesrpace (empty)

Types of Energy!! Energy that is stored in matter. Potential Energy Kinetic Energy Mechanical Energy Electrical Energy Sound What is it? Draw a picture: Energy that is stored in matter. Energy from produced by sound vibrations Energy of movement Energy from moving parts of a machine Energy that comes from electrons moving in a substance
