Average Speed
Speed measured over a certain distance for a certain time
Momentum
The quantity of motion of a moving body, measured as a product of its mass and velocity
Displacement
A way to measure motion that only looks at starting and ending points
Gravity
The force that attracts a body toward the center of the earth, or toward any other physical body having mass
Constant Speed
A speed that does not change over time
Vertical Motion
Any motion that is perpendicular to the earths surface and occurs naturally due to gravity
Velocity
Speed in a given direction
Newtons 1st law
Law of inertia, object at rest will stay at rest unless acted upon by an outside force
Force
Any push or pull on an object
Speed
A rate of change in a position over time
Friction
An attraction between two bodies
Centripetal Force
A force acting toward the center of a circular path
Acceleration
The rate of change in an objects velocity
Newtons 2nd law
Law of acceleration
Circular Motion
Anything that travels in a circular path
Horizontal Motion
Any motion that is parallel to the earths surface and occurs naturally due to gravity
Instantaneous Speed
A speed is given at a precise moment in time
Newtons 3rd law
Law of reciprocal actions
Projectile
Anything that is thrown or shot in the air
Distance
A way to measure the exact path an object takes
Terminal Velocity
Relationship between gravity pulling down and air resistance up or the maximum speed an object will reach in free fall
Conservation of Momentum
Total momentum within a system will start constant unless acted upon by am outside force
