Motion『••✎••』

Distance equation

d=s x t

Speed equation

S=d/t

Time equation

T=d/s

Speed

The amount of distance moved per time

Speed units

Unit= mi/hr, meters per second, kilometers per hour (any distance and time)

Units for velocity

Mi/hr North, m/s to the left, km/h East, cm/min upward, yd/s to the right

Acceleration

The amount that velocity changes per unit of time (could be speeding up, slowing down, or changing direction)

Units for acceleration

mi/hr per second (mi/hr/s), m/s/s, or ms², km/per minute (km/h/min)

Acceleration

A = (vf-vi)/t

Velocity initial (the 1st)

Velocity final (2nd)

Motion

When an object changes direction or distance with their reference point over time
