Explanation:
motion- when a body changes its state by respect of interval time or other references is said to be motion
there are two types of motion- uniform and non uniform motion
uniform motion- when the object covers equal distance in equal intervals of time . it is said to be uniform motion.
non uniform motion-when the object covers equal distance in unequal intervals of time is said to be non uniform motion.
speed-speed of a body is defined by distance covered by it in given time taken
average speed - the average speed of a body is the total distance travelled divided by the total time taken to cover the distance.
velocity- velocity is the ratio of total displacement covered by a body in given time taken
acceleration - it is the rate change of velocity with time .
uniform acceleration- if a body travels in straight line and its velocity increases by equal amount in equal intervals of time ,is said to be uniform acceleration
non uniform acceleration- if a body travels with velocity increases by unequal amounts in equal intervals of time.
