For every action, there is an equal and opposite reaction.
Forces are measured in this unit.
Newtons
The rate of change in velocity over time.
Acceleration
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.
This is a fixed point against which the position of an object can be measured.
Reference Point
Newton's 3rd Law of Motion
"Every action has an equal and opposite reaction."
These forces result from squeezing an object.
Compressional Forces
This is the property of a moving object that depends on its mass and velocity.
Momentum
If the area which a force is exerted increases, what happens to the pressure?
It decreases
What creates acceleration?
Unbalanced Force
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
What creates acceleration?
Unbalanced Force
What is the acceleration of gravity, in number form?
9.8 m/sec2
What is Pascal's Principle?
Calculate the gravitational force for an object with a mass of 1500 g.
14,700 N
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.
If an object isn't moving, this is probably 0.
Net Force
This is the change of velocity of an object traveling in a circular path.
Centripetal Acceleration
What two forces create the curved path of projectile motion?
Horizontal and Vertical Motion
This is the curved path an object follows when it is thrown or propelled near Earth's surface.
Projectile Motion
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.
Name the four fundamental forces.
Weak radioactive forces
Strong radioactive forces
Gravity
Electromagnetic forces
When an object is falling, the point where it stops accelerating and starts falling at a constant speed is called ________.
Terminal Velocity
This device works similarly to a Hydraulic device, except it uses air.
Pneumatic Device
The design of aircraft wings is called ______.
Airfoil
