Definition

the abillty to make a change or do work


EX: Electricity, Kinetic energy.

Term

POTENTIAL ENERGY

[image]

 

Definition

Stored energy that resaults from the position or shape of an object.

EX: A book has stored energy that we dont see because its not moving, it will use that energy when it moves.

Term

ELASTIC POTENTIAL ENERGY

[image]

Definition

Potential energy stored as a result of deformation of an elastic object

EX: the stretching of a spring

Term

KINETIC ENERGY

[image]

Definition

Energy in an object due to its motion

 

EX: When wind strikes a leaf, the leaf moves, and that movement is a change

Term

GRAVITATIONAL POTENTIAL ENERGY

[image]

Definition

Potential energy that depends on an obeject's height.

EX:Throwing a ball from the ground to the roof will take longer time from the roof to the ground

 

Term

MACHANICAL ENERGY

[image]

Definition

The KE or PE of an object due to its motion or due to its position

EX: The roller coaster .

Term

THERMAL ENERGY

[image]

Definition

 The energy a substance or system has related to its temperature.

EX: the sun, FIRE, volcano lava

Term

CHEMICAL ENERGY

[image]

 

Definition

Energy stored in chemical bonds

EX: 1.Light Bulbs

2.Plants changing the water and sunlight etc to form AIR (Photosynthesis)

Term

LAW OF CONSERVATION OF ENERGY

[image]

Joule James: who found (made) the law

Definition

The rule that energy can't be created or destroyed

EX: No human can creat electricity out of nothing, you can't destroy kinetic energy.

Term

RADIATION

[image]

Definition

The transfer of energy by electromagnetic waves.

EX: Light.

Term

ENERGY TRANSFORMATION

 

[image]

Definition

The process of changing one form of energy to another.

EX: While biking the energy transforms for PE or KE, if you are moving, you are making KE, but when you stop, you change KE to PE.

Term
