speed- the speed of an object is defined as the distance travelled in metre per second

velocity- the speed in which the the object moves in particular direction

momentum- the ability to keep increasing or aur developing the force that makes something move faster and faster

The SI unit of momentum is kilogram

THE FIRST Equation OF MOTION IS

v=u+at

drive the first equation of motion

v=final velocity

u=initial velocity

a=accelerate

t=time
