Topic: Kinetic and potential energy
SLANT: KINETIC AND POTENTIAL ENERGY
energy is the ability to cause change
energy is measured in a unit called the joule
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
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
Elastic potential energy: energy stored in objects that are compressed or stretched
chemical potential energy: energy stored in chemical bonds between atoms
fuels like gasoline and wood
Read Energy and Work
What two factors determine how much work is done?
List three examples of how you can do work on an object?
You may work on the flash cards if time permits.
