100
The smallest unit of matter that has the properties of that element
What is an atom?
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
Two or more atoms bonded together that can only be broken down by chemical reaction
What is a molecule
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
A change in the state of matter and dissolving are examples of this
What is a physical change?
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
Gas bubbles, change in temperature, and formation of a precipitate are indicators of this
What is a chemical change?
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
On the periodic table you can find similar elements here
What is in a group?
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
