When you rub your hands together, mechanical energy is transformed into this type of energy.

What is thermal (heat) energy?

100
The wave with the longest wavelength/lowest frequency in the visible spectrum
What is red?
100
Some useful energy is "lost" as this form of energy during all energy transformations
What is thermal energy?
100
A force that always opposes the motion of an object
What is friction?
100
distance/time
What is the formula to calculate speed?
200

When you turn on a lamp, electrical energy is transformed into this main form of energy that allows you to see.

What is light energy?

200
The EM wave with the shortest wavelength/highest frequency/highest energy
What is a gamma ray?
200

Energy resulting from movement of atoms and molecules

What is thermal energy?

200
The sum of all forces acting on an object
What is net force?
200
Any straight line on a distance time graph represents an object doing this
What is moving at a constant speed
300

When you turn on a flashlight, electrical energy changes into these two forms of energy.

What are light energy and thermal (heat) energy?

300
Waves in the EM spectrum that have the longest wavelength/ lowest frequency/lowest energy
What are radio waves?
300
The total kinetic and potential energy of a large scale object
What is mechanical energy?
300
electrical, magnetism, and gravitational forces
What are non-contact forces (all others will be contact forces)
300
On a distance-time graph, a horizontal line represents an object that is doing this
What is staying at rest?
400

This law states that energy cannot be created or destroyed, only changed from one form to another.

What is the law of conservation of energy?

400
Sound travels fastest in this because it is a mechanical wave
What is a solid? The more dense the particles, the faster the sound wave travels
400
At it's highest point before motion begins, an object has 100% of this form of energy
What is potential energy?
400
Two forces acting on different objects that are equal strength but opposite in direction
What are force pairs?
400
An object in motion will do this when the forces acting on it are balanced
What is move at a constant speed in a straight line?
500

A bouncing ball never returns to its original height because some of its mechanical energy is transformed into these two forms of energy during each bounce.

What are thermal (heat) energy and sound energy?

500
The change in wave direction that causes an object to appear bent in water as a light wave slows down
What is refraction?
500
When a ball is falling, the lowest point will have 100% of this form of energy
What is kinetic energy?
500
Force = mass x acceleration
What is Newton's 2nd law
500
An object that has unbalanced forces acting on it must be doing this
What is accelerating (speeding up, slowing down, changing direction)?
