Velocity
The quantity that requires both magnitude and direction.
Acceleration
Measures the rate of change of an object's velocity.
Average Speed
Calculated as distance divided by time.
SI Units of Speed
Meters per second (m/s).
SI Unit of Force
Newton (N).
Work
The transfer of energy from one place to another, calculated as force multiplied by distance.
Power
The rate of energy transfer.
Formula for Work
W = F × d, where W is work, F is force, and d is distance.
Unit of Power
Watts (W), equivalent to joules per second (J/s).
Force Application
A force can be a push or a pull.
Newton's Second Law
Explains why 1 N is equal to 1 kg·m/s².
Average Acceleration
Change in velocity divided by the time over which the change occurs.
