This type of change creates a new substance.
Chemical change
A push or pull on an object is called this.
Force
When forces are equal in size and opposite in direction, they are ____.
Balanced
Newton’s 3rd Law says for every action, there is an equal and opposite ______.
Reaction
Energy of motion is called this.
Kinetic energy
Energy cannot be created or destroyed; it can only do this.
Transform or transfer
Bubbling, temperature change, and color change are signs of this.
Chemical reaction
Force measured in Newtons uses this symbol.
N
Balanced forces cause this amount of motion.
No motion / no change in motion
A rocket launches because gases push downward while the rocket does this.
Moves Upward
Stored energy due to position is called this.
Potential energy
When potential energy decreases, this type of energy increases.
Kinetic energy increases
Burning wood is an example of this type of change.
Chemical change
The force that pulls objects toward Earth.
Gravity
Unbalanced forces cause an object to do this.
Speed up, slow down, or change direction
When you push on a wall and feel it push back, this law is shown.
Newton’s Third Law
A roller coaster at the top of a hill has the most of this energy.
Potential energy
The highest point of a transverse wave.
Crest
Rusting is also known as this scientific process.
Oxidation
This force slows motion when two surfaces rub.
Friction
A book sliding across the table slows down because this force is unbalanced.
Friction
A balloon rocket moves forward because air rushes out in this direction.
Opposite direction
A faster-moving object has more of this type of energy.
Kinetic energy
The spread-out area in a longitudinal wave.
Rarefaction
The only way to reverse a true chemical change.
You cannot reverse a chemical change by physical means
A force that acts without touching an object, like magnetism.
Non-contact force
A person standing still has ___ forces acting on them.
Balanced
The two forces involved in Newton’s 3rd Law are called an action force and this.
Reaction force
Stretching a rubber band increases this kind of potential energy.
Elastic potential energy
Matter in a wave does not move forward; instead, it does this.
Vibrates in place
