Energy Types
This is the energy of motion; the faster an object moves, the more of this it has.
What is kinetic energy?
This law states that energy cannot be created or destroyed, only transformed or transferred.
What is the Law of Conservation of Energy?
In this type of wave, the medium moves perpendicular to the direction the wave travels (it looks like a "wiggle").
What is a transverse wave?
This force pulls all objects toward the center of the Earth.
What is gravity?
If a box is pushed 10N to the right and 10N to the left, the forces are described as this.
What is balanced?
A stretched rubber band or a compressed spring holds this specific type of potential energy.
What is Elastic Potential Energy?
In a simple circuit, electrical energy is often transformed into these two types of energy in a lightbulb.
What are light (radiant) and heat (thermal) energy?
Sound waves travel this way, with particles compressing and expanding in the same direction the wave moves.
What is a longitudinal wave?
This force opposes motion when two surfaces slide against each other.
What is friction?
When the Net Force on an object is NOT zero, the object will do this.
What is accelerate (or move/change motion)?
Energy stored in the bonds of food, batteries, or fuels.
What is Chemical Potential Energy?
In a food web, this is the original source of energy that plants transform into chemical energy.
What is the Sun (or Radiant energy)?
The highest point of a transverse wave is called the crest; this is the name for the lowest point.
What is the trough?
This "support force" acts upward on an object resting on a surface, like a book on a table.
What is normal force?
If a car is pushed with 50N of force North and 20N South, this is the Net Force.
What is 30N North?
An object’s potential energy increases as its height above the ground increases, due to this force.
What is Gravitational Potential Energy?
During photosynthesis, radiant energy from the sun is transformed into this.
What is chemical energy?
In a longitudinal wave, the area where particles are spread apart is called this.
What is rarefaction?
This type of force can push or pull objects without touching them, specifically using North and South poles.
What is magnetism?
Newton’s Third Law states that for every action, there is an equal and ______ reaction.
What is opposite?
As a roller coaster drops from the top of a hill, this specific energy transformation occurs.
What is Potential to Kinetic Engergy
In an amusement park ride, some mechanical energy is always "lost" to the environment in this form due to friction.
What is thermal energy?
Waves transfer this from one place to another without transferring matter.
What is energy?
A person pushing a heavy box across the floor is an example of this specific force.
What is applied force?
According to Newton’s Third Law, if you jump off a small boat, the boat moves backward because of this.
What is a force pair (or action-reaction pair)?
