    • next blank page

    • SLANT

  • Topic: Kinetic and potential energy

Lesson:

SLANT: KINETIC AND POTENTIAL ENERGY

  1. energy is the ability to cause change

    • energy is measured in a unit called the joule

  2. kinetic energy is energy due to motion.

    • It is affected by speed and mass

    • as speed increases so does kinetic energy

    • as mass increases so does kinetic energy

    • examples…

  3. Potential energy is energy that is stored due to interactions between objects or particles.

    • Gravitational potential energy: energy stored by the attraction between two object’s due to gravity

    • depends upon mass, the acceleration due to gravity, and height

    • weight is mass x gravitational acceleration

    • PE = Mass ∙ Gravitational Acceleration ∙ Height

    • PE = Weight ∙ Height

    • examples…

  4. Elastic potential energy: energy stored in objects that are compressed or stretched

    • rubber band

  5. chemical potential energy: energy stored in chemical bonds between atoms

    • fuels like gasoline and wood

    • food

Independent Work:

Read Energy and Work

  1. Define work.

  2. What two factors determine how much work is done?

  3. List three examples of how you can do work on an object?

You may work on the flash cards if time permits.
