What is the word which means a push or pull that acts on an object?
A force
100
What us a force that acts between any two masses? Or in other words, why do leaves fall to the ground?
What is Gravity.
100
What is the product of an object's mass and its velocity?
Momentum
100

Gravity
200
What is force measured in?
Newtons
200
What is the motion of a falling object after it is given an initial forward velocity?
Projectile motion
200
What is the law which states that if no net force acts on a system, then the total momentum of the system does not change.
Law of conservation of momentum.
200
What is Newton's First Law of Motion?
The state of motion of an object does not change as long as the net force acting on the object is zero.
200
What is the product of an object's mass and its velocity?
Momentum
300
What is net force?
The overall force acting on an object after all the forces are combined?
300
What is the tendency of an object to resist a change in its motion?
Inertia
300
What are the only forces that can both attract and repel?
Electric force and magnetic force.
300
What is Newton's second law of motion?
The acceleration of an object is equal to the net force acting on it divided by the object's mass.
300
The overall force acting on an object after all the forces are combined?
Net force
400
What is friction?
What is a force that opposes the motion of objects that touch as they move past each other.
400
What is the measure of the inertia in an object?
Mass
400
What two forces act within the nucleus to hold it together?
Strong nuclear force and weak nuclear force.
400
What is Newton's third law of motion?
Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object.
400
What is the measure of the inertia in an object?
Mass
500
What are the two types of friction?
Static Friction, Sliding Friction, Fluid Friction and Rolling Friction
500
What is the measure of force of gravity acting on an object?

500
What is the force which continuously changes the direction of an object to make it move in a circle. (Hint:water in a pail)
Centripetal force
500
What does Newton's law of universal gravitation state?
That every object in the universe attracts every other object.
