Definition
 The amount of matter within an object
Term
 Volume
Definition
 The amount of space an object occupies.
Term
 Weight
Definition
 A measure of gravitational pull on an object.
Term
 Water Displacement
Definition
 A means of finding the volume of an irregular shaped object. A graduated cylinder, water and sometimes a displacement vessel is used.
Term
 Hypothesis
Definition
 An educated guess on what you expect to happen.
Term
 Constant Speed/Velocity
Definition
 Speed or Velocity that does NOT change over time. Causes a ZERO acceleration.
Term
 Average Speed/Velocity
Definition
 The total distance and object travels divided by the total time it takes to get there.
Term
 Instantaneous Speed/Velocity
Definition
 The speed or velocity of an object at an exact moment in time.
Term
 Displacement
Definition
 The exact path an object takes. Only looking at starting and ending points.
Term
 Distance
Definition
 The entire path an object takes. This is always positive and always growing.
Term
 Velocity
Definition
 Speed in a given direction.
Term
 Speed
Definition
 The rate of change in an objects position. aka....how fast you are going.
Term
 Acceleration
Definition
 The rate of change in an objects velocity.....aka...how much you are speeding up or slowing down.+ = Speeding Up- = Slowing Down0 = Constant Velocity
Term
 Momentum
Definition
 A physical property all objects with mass and velocity have.
Term
 Friction
Definition
 Force that opposes all motion
Term
 Force
Definition
 Any push or pull
Term
 Terminal Velocity
Definition
 When the acceleration due to gravity on an object balances out with it's air resistance
Term
 Conservation of Momentum
Definition
 The total p of a system will always stay constant #uaubaof
Term
 Centripetal Force
Definition
 A force acting toward the center of any object traveling in a circle
Term
 Projectile
Definition
 anything that is thrown or shot through the air
Term
 Circular Motion
Definition
 Any object traveling in a circular path
Term
 Vertical Motion
Definition
 Any motion perpendicular to the earth's surface
Term
 Horizontal Motion
Definition
 Any motion parallel to the earth's surface
Term
 Newton's 1st Law
Definition
 An object at rest will stay at rest or an object in motion will stay in motion #uaubaof
Term
 Newton's 2nd Law
Definition
 A force will accelerate in the direction of the force (F = m * a)
Term
 Newton's 3rd Law of Motion
Definition
 For every action there is an equal and opposite reaction
Term
 Gravity
Definition
 An attraction between two bodies. More mass = more gravity and More distance = Less Gravity
