What is motion
Velocity
Eqations of motion
When a body changer its position with respect of its surroundings and time.
The point from where the motion of a body is defined is called the refernce point
Speed with direction or Rate of change of displacement s/t - where s is displacement and t is time

Uniform
Non uniform
Speed
The rate of change of distance. d/t where d is distance and t is time
Where distance travelled is equal in equal intervals of time
Where distance travelled is not equal in equal intervals of time
Rate of change of velocitiy. (v-u)/t where v is final velocity and u is initial velocity and t is time
2as = v x v + u x u
v= u + at
s = u - (a x t x t)/2
In v-t graph slope of graph(y2-y1/x2-x1) is acceleration and area under the graph is displacement
In a-t graph area under the graph is velocity
In s-t graph slope of graph(y2-y1/x2-x1) is velocity
