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
