Speed
= d/t = distance/time
Distance
= s x t = speed x time
Time
= d/s = distance/speed
Velocity is Speed
But with direction (Ex: m/s east)
Acceleration
(Final velocity - starting velocity) / time
Force
= Mass x acceleration = ma
Rate is the same thing as
Speed
Units for speed
mph (miles per hour), m/s (meters per seconds)
Units for acceleration
m/s² (meters per seconds squared)
Units for mass
kg (kilograms), g (grams)
Units for force
N (newtons)
Units for distance
m (meters), km (kilometers), miles
Units for time
s (seconds), min (minutes), hr. (hours)
Units
A quantity or amount choosen as a way to measure, such as dollars, hours, or grams.
Momentum
p= m x v = mass x velocity
Units for momentum
kg • m/s south (kg times meters per second south(with direction))
Final velocity
Vf = Vi + acceleration x time
(Final velocity equals initial velocity plus acceleration x time)
