Energy Vocabulary Unit 2. 1 Advanced Version

Introduction to Energy • https: //www. youtube. com/watch? v=CW 0_S 5 Yp. YVo

Energy • The ability to do work or cause change. (Work – the movement of an object through a distance).

What is energy really? • https: //www. youtube. com/watch? v=j. Cr. Ot. F 7 T 4 HE

The Law of Conservation of Energy • In physics, the law of conservation of energy states that the energy can not be created or destroyed, only transformed.

Kinetic Energy • Energy resulting from the motion of an object. The amount of kinetic energy an object has is determined by the mass and speed (velocity) of the object.

Potential Energy • This is stored energy. An object has potential energy because of its position or composition. • Ex: A bike on top of a hill.

Energy Transformation • Energy can be transformed (changed) from one form to another. • EX: Flipping a switch to turn on a light.

Energy Transformation Examples • https: //www. youtube. com/watch? v=MIq. Sg 4 JSJt 8

Mechanical Energy • The energy associated with the motion of an object. • EX: Tossing a ball in the air.

Elastic Potential Energy • Stored as a result of deformation of an elastic object, such as the stretching of a spring.

Gravitational Potential Energy • Energy an object possesses because of its position in a gravitational field.

Friction • A force that opposes the motion of an object. Friction is present when two objects are in contact with one another.

Joule • The standard unit of work or energy in the International System of measurements (SI), equal to the work done by a force of one newton when its point of application moves through a distance of one meter in the direction of the force: equivalent to 10 7 ergs and one watt-second. • EX: One joule is equal to the work it takes to make a watt of power for a second. In physics, it's common to talk about joules of energy — one example used to illustrate a joule is lifting an apple, which weighs about one Newton.
