Answer : a quantitative description of kinematics involves using position , time velocity and acceleration to describe the motion.
Explanation : Kinematics are mostly concerned with the geometrically possible motion of an object without consideration of the force and mass involved.
it is used to describe the position of the object , their velocities, time and their acceleration.
we know the equations of motion.
....(I)
....(II)
....(III)
Where, v = velocity
t = time
a = acceleration
s = position , distance
