Term
Gravity
Definition
Weakest Force
Works across the entire universe
All masses have gravitational force on other masses
Term
Velocity
Definition
Speed in a direction
Term
Speed
Definition
Distance traveled in a specific time
Term
Direction
Definition
What way movement is happening in
Term
Acceleration
Definition
Any change of motion in either speed or direction
change of velocity/time required for change
Term
Force
Definition
A push or pull
Term
Mass
Definition
Amount of matter
Term
Newton's First Law
Definition
Objects will remain in a state of uniform motion until acted on by an outside force.
Term
Newton's Second Law
Definition
Force=mass*acceleration
Term
Newton's Third Law
Definition
All actions or forces have an equal and opposite reaction or force.
Term
Falling
Definition
Falling objects in a vacuum will accelerate at the gravitational constant.
Term
Orbiting
Definition
Balance between movement of the Earth and the rate of falling. The satellite just keeps falling past the Earth, can't catch it.
Term
Vertical Throw
Definition
The object slows down at the gravitational constant, until it comes to a stop. Then it accelerates down also at the gravitational constant.
