Describe Newton's 1st Law of Motion. Tell what it says and what it is commonly called. 

law of inertia. Object in motion stays in motion or an object at rest stays at rest UNLESS acted on by a FORCE.  

100
What is the force that holds the nucleus together?
Nuclear Force (strong and weak)
100
The mass of a newborn baby is 4.2kg. What is its weight?
41.16N
100
How are kinetic and potential energy different?
Kinetic energy is the energy of motion of an object. Potential energy is energy stored due to the position or shape of an object
100

You push a box and it doesn't move, what force is opposing you?

static friction
200
Describe Newton's Second Law of Motion. Tell what it says and what it is commonly called. 

F=ma. Force equals the product of an object’s mass and acceleration. (or Acceleration is equal to the force and inversely proportional to mass)

200
What force is responsible for the orbits of the planets in the solar system?
gravitational force
200
What is the SI unit for force?
Newton (N)
200
Name the six kinds of simple machines.
lever, wheel and axel, inclined plane, wedge, screw, pulley
200
List the types of sliding friction from weakest to strongest
rolling, sliding, static
300
Describe Newton's 3rd Law of Motion. What it is commonly called and what it says.

Action/Reaction law. For every action there is an equal and opposite reaction.  

300
What particles does the strong nuclear force act on?
protons and neutrons
300
How are mass and weight different?
mass is a measure of the inertia of an object; weight is a measure of the force of gravity acting on an object.
300
What formula relates work and power?
Power=work/time
300

An object has a mass of 8.0 kg and is accelerating at a rate of 5 m/s. What is the force of the object?

40N
400

What is the sum of the forces on an object that is NOT balanced?

Net Force 
400
The moon in its orbit around Earth behaves like a ball at the end of a string being swung above your head. Explain the force involved.
Earth's gravitational attraction acts as a centripetal force on the moon
400
What causes projectile motion?
The combination of an initial forward velocity and the downward vertical force of gravity.
400

A 15 kg ball accelerates at 20 m/s2 what force was exerted on the ball?

300N
400

An object is being pushed with a force of 50 Newtons, and has a mass of 25 kg. What is the acceleration of the object?

2 m/s2

500

What is a force that opposes motion?

Friction
500
Describe Newton's Law of universal gravitation.
States that every object in the universe attracts every other object.
500
The energy of a moving object is called?
kinetic energy
