This is a system of objects that are not moving with respect to one another.

What is a frame of reference?

100

This is the ratio of distance an object moves to the amount of time the object moves.

What is speed?

100

This is the unit of measurement used for Force.

What is a Newton?

100
This law of motion states that the acceleration of an object is equal to the net force acting on it divided by the object's mass.

What is Newton's Second Law?

100

The result of a force distributed over an area is:

What is pressure?

200

This is defined as "the length of the path between two points."

What is distance?

200
Speed and direction combine together to tell us the object's ____________

What is velocity?

200

The overall force acting on an object after all the forces are combined is known as _________

What is net force?

200

This law of motion states that the state of motion of an object does not change as long as the net force acting on the object is zero.

What is Newton's First Law?

200

A change in pressure at any point in a fluid is transmitted equally and unchanged in all directions throughout the fluid. This illustrates:

What is Pascal's Principle?

300

This is a quantity with both magnitude and direction.

What is a vector?

300

This is the rate at which velocity changes.

What is acceleration?

300

The force that acts on objects that are not moving is:

What is static force?

300

This is the force of gravity acting on an object.

What is weight?

300

As the speed of a fluid increases, the pressure within the fluid decreases. This illustrates:

What is Bernoulli's Principle?

400

This is movement in relation to a frame of reference.

What is relative motion?

400
The movement of an object toward Earth solely because of gravity is known as:

What is free fall?

400

This force opposes the direction of motion of an object as it slides over a surface.

What is sliding force?

400

This law of motion states that 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 Third Law?

400

This principle states that the buoyant force on an object is equal to the weight of the fluid displaced by the object.

What is Archimedes' Principle?

500

This is the vector sum of two or more vectors.

What is a resultant vector?

500

The rate at which an object is moving at a given moment in time is:

What is instantaneous speed?

500

The curved path which an object follows when thrown is:

What is projectile motion?
500

The product of an object's mass and its velocity is:

What is momentum?

500

This upward force acts in the opposite direction of gravity.

What is buoyant force?
