Unit 3 : Acceleration And FreeFall

Unit for Speed

m/s

Unit for Acceleration

m/s^2

Scalar quantity

Has only magnitude, no direction

Vector quantity

Has both magnitude and direction

Position

Allows to determine if a motion occurred

FreeFall

Any object that's falling under the influence of gravity

Acceleration

Change in velocity

Constant Speed

Continuous speed, speed that doesn't change

Speed

Distance an object moves per unit of time

Gravity

Force that pulls objects downward at rate of 9.8 m/s^2

Time

How fast an object goes

Distance

How much ground an object has covered

Unit for Distance

Meters

Reference point

Place or object used for comparison to determine if motion occurred

Unit for Time

Seconds

Velocity

Speed in direction

Instantaneous Speed

Speed of an object moves at a given instant time

Velocity time graph

Tell the speed of an object in a given period of time.

Average Speed

Total distance traveled by the total time

Motion

When an objects position changes relative to another
