Define the terms Acceleration & Velocity?
Velocity is defined as the rate of change of displacement with respect to time. It is nothing but the speed at which an object moves in a particular direction. It is a vector quantity. It needs both magnitude and direction to represent it. Mathematically, velocity is given as $velocity =\frac{displacement }{ time}$ The units of velocity are meter/second (m/s).
Acceleration is the rate of change of velocity. If the speed of an object is increasing, we can say the object is accelerating. Mathematically, acceleration is given as
$a\ =\ \frac{v\ -\ u}{t\ }$
Where a = acceleration,
v = final velocity,
u = initial velocity, and
t = time taken
