NEWTON'S LAWS
100
Unit of measure for energy and work.
Joule
100
Two types of potential energy
Elastic and gravitational
100
Overall force that acts on an object after all forces have been combined.
Net force
100
Strongest universal force
Strong nuclear
100
Other name for Newton's first law.
Law of Inertia
200
Formula for kinetic energy
KE = 1/2mv^2
200
Type of energy that travels through space in the form of waves.
Electromagnetic
200
Unit of force
Newton
200
Type of friction which make it possible to walk across the floor.
Static
200
Formula for Newton's second law.
Acceleration = Net force/mass

300
Force is represented by this.
Arrow (length and direction)
300
Weakest but most widespread universal force.
Gravitational (gravity)
300
Product of an object's mass and the gravitational force to which it is subjected.
Weight
400
Sum of an object's potential and kinetic energy.
Mechanical
400
Equivalent of energy, according to Einstein.
Mass
400
Type of forces that result in a zero net force.
Balanced
400
My desk chair has this type of friction
Rolling
400
Why don't action - reaction forces cancel each other out?
Because they act on different objects
