Category 1
Any push or pull on by object on another
force
A noncontact force that acts over a distance. Pulls objects towards each other.
gravity
Friction
The pushing of air against another object
Air Resistance
How fast an object is moving
Speed
The formula to find a speed of an object
Speed = Distance divided by Time
S=D/T
The decrease in rate of change in an object's position
deceleration
The rate of change in velocity of an object, or just a fancy word for speeding up.
Acceleration
When two forces act on an object with equal strength
Balanced Force
A measure of the amount of matter in an object
Mass
Material that does not let any light pass through because the light is absorbed is
A: Transparent
B: Translucent
C: Opaque
C: Opaque
Energy that is moving
Kinetic Energy
Light bouncing off an object
Reflection
Energy that is stored in an object to be used
Potential Energy
True or False: Nothing travels faster than light
True
The bending of light as it passes from one material to another
Refraction
Material that lets all light pass through
A: Transparent
B: Translucent
C: Opaque
A: Transparent
When one force acting on an object is stronger than another force it causes an object to move.
Unbalanced Force
Volume
Any substance through which sound travels
Which law of motion is the greater the mass, the more force it takes to accelerate that object
Newton's 2nd Law of Motion
Light hits an object and is taken in by that object
Absorption
An object in motion tends to stay in motion and an object at rest tends to stay at rest unless acted upon by an outside force (Which Newton's Law of Motion is this)
Newton's 1st Law of Motion (Inertia)
How high or low a sound is
Pitch
Which Newton's Law is for every action there is an equal or opposite reaction?
Newton's 3rd Law of Motion
