Physics

Motion

Occurs when an object changes “position.”

Relative Motion

Occurs relative to your environment

Distance

How far an object moves

Displacement

Distance and direction of an object’s change in position from a starting point

Speed

Distance an object travels per unit of time

S=D/T

Speed= Distance/ Time

SI unit for speed

meter per second (m/s)

SI unit for time

Second (s)

SI unit for distance

Meter (m)

Average speed= total distance/ total time

Average speed is the total distance traveled divided by the total time of the trip

Instantaneous speed

The speed given at one particular point in time

(Such as; instant)

Speed can’t be negative

Because distance travelled and time can’t be negative values

Velocity

Speed+ Direction

Includes the speed of an object and the direction of the objects motion

Velocity can be negative

Movement in the opposite direction from the positive, such as left instead of right, or down instead of up, showing the speed.

Velocity Formula

V= (Pf-Pi)/T

SI unit for Displacement

Distance+ Direction
