displacement, velocity, acceleration, force, position

length: metres (m) time: seconds (s) mass: kilograms (kg)

Distance is the total length of the actual path between two points. Displacement is the length and direction of a straight line between starting and ending points.

The distance an object travels in a given time interval

distance travelled along an objects path divided by the time it takes to travel that distance

how far an object has been displaced in a given time interval

displacement of an object divided by the time it takes to travel this distance

velocity = displacement/time

speed = distance/time

the velocity of an object in motion at a specific point in time

The rate at which velocity changes

change in velocity/change in time

a=vf-vi/t

directly: displacement at given time slope: denotes object's velocity, straight = constant horizontally straight line: v = 0m/s area under graph: n/a

directly: velocity at given time slope: denotes the object's acceleration horizontally straight line: a = 0m/s area under the graph: distance the object has moved from origin

a standard relative to which motion and rest may be measured

Vr = Vo - Vd

where r is the relative velocity of the observer relative ro the distance object (o relative to d)

o is the observer

d is the distant object

s = ut + 1/2*at^2 v = u + at v^2 = u^2 + 2as

when a is constant and v is changing

S - displacement U - initial velocity V - final velocity A - acceleration T - time
