What is a newton?
100
The fluid friction acting on an object moving through the air
What is air resistance?
100
An object at rest remains at rest and an object in motion remains in motion, unless acted unpon by an unbalanced force.
What is Newton's first law of motion?
100
An attractive force between any two objects.
What is gravitational force?
100
The product of an object's mass and it's velocity.
What is momentum?
200
A push or a pull that acts on an object
What is a force?
200
The friction force that acts on rolling objects.
What is rolling friction?
200
Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object.
What is Newton's 3rd law of motion?
200
A force associated with charged particles, which has two aspects, electric force and magnetic force.
What is electromagnetic force?
200
The curved path of a falling object in free fall after it is given an initial forward velocity.
What is projectile motion?
300
The overall force acting on an object after all the forces are combined.
What is net force?
300
The friction force that acts on objects that are not moving.
What is static friction?
300
The acceleration of an object is equal to the net force acting on it divided by the object's mass.
What is Newton's 2nd law of motion?
300
A powerful attractive force that binds protons and neutrons together in the nucleus.
What is strong nucleus force?
400
A friction force that opposes the motion of an object through a fluid.
What is fluid friction?
400
The tendency of an object to resist change.
What is inertia?
400
A powerful attractive force that acts over a short range.
What is a weak nuclear force?
400
The constant velocity of a falling object when the force of air resistance equals the force of gravity.
What is terminal velocity?
500
A force that opposes the direction of the motion of an object as it slides over a surface.
What is sliding friction?
500
A force that continuously the direction of an object to make it move in a circle.
What is centripetal force?
500
The law stating that the total momentum of a system does not change if no net force acts on the system.
