Motion and Force
Push or pull acting on an object
Force
Energy that is stored and ready to be used
Potential
T or F: Energy can be created out of nothing
False
Rate at which an object covers distance over time
Speed
Energy of motion
When a skateboarder rolls down a hill, potential energy decreases and this energy increases
Kinetic
Force that pulls objects towards the center of the Earth
Gravity
Energy produced by vibrating objects that you can hear
Sound energy
When you rub your hands together, mechanical energy transforms into this type of energy
Thermal
Force that resists motion when two surfaces rub against each other
Friction
Internal energy of an object related to its temperature of movement of particles
Thermal energy
As an object gets higher off the ground, this type of PE increases
Gravitational PE
An object at rest stays at rest and an object in motion stays in motion, unless acted upon by this type of force
Unbalanced
Energy stored in bonds of molecules in food, batteries, and fuel
Chemical energy
Standard scientific unit used to measure energy
Joule
