Newton's 3rd Law of Motion States:

For every action, there is an equal and opposite reaction.

100

Forces are measured in this unit.

Newtons

100

The rate of change in velocity over time.

Acceleration

100

How do thrust and drag relate to each other.

Thrust moves a plane forward and drag is the friction that works in opposition to thrust.

100

This is a fixed point against which the position of an object can be measured.

Reference Point

200
How rockets are propelled can be explained by which of Newton's laws?

Newton's 3rd Law of Motion

"Every action has an equal and opposite reaction."

200

These forces result from squeezing an object.

Compressional Forces

200

This is the property of a moving object that depends on its mass and velocity.

Momentum

200

If the area which a force is exerted increases, what happens to the pressure?

It decreases

200

What creates acceleration?

Unbalanced Force

300

This is the tendency of an object to resist a change in its movement.  Also heavily applies to Newton's 1st Law of Motion.

Inertia

300

What creates acceleration?

Unbalanced Force

300

What is the acceleration of gravity, in number form?

9.8 m/sec2

300

What is Pascal's Principle?

A change in pressure at any point in a fluid results in an equal change everywhere in the fluid.
300

Calculate the gravitational force for an object with a mass of 1500 g. 

14,700 N

400

Newton's 2nd Law of Motion states:

The acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.

400

If an object isn't moving, this is probably 0.

Net Force

400

This is the change of velocity of an object traveling in a circular path.

Centripetal Acceleration

400

What two forces create the curved path of projectile motion?

Horizontal and Vertical Motion

400

This is the curved path an object follows when it is thrown or propelled near Earth's surface.

Projectile Motion

500

Newton's 1st Law of Motion states:

An object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.

500

Name the four fundamental forces.

Weak radioactive forces

Strong radioactive forces

Gravity

Electromagnetic forces

500

When an object is falling, the point where it stops accelerating and starts falling at a constant speed is called ________.

Terminal Velocity

500

This device works similarly to a Hydraulic device, except it uses air.

Pneumatic Device

500

The design of aircraft wings is called ______.

Airfoil
