Question

Differentiate between speed, velocity and acceleration

Answer 1

Speed is the rate of change of distance(basically how much distance(m) has been covered in a particular time(s)). Velocity is the rate of change of displacement( change of distance in a particular direction with respect to time) , and acceleration is the rate of change of velocity per unit of time.(Amount of increase or decrease in velocity). Also, speed is a scalar quantity but velocity and acceleration are vector quantities.

Answer 2

speed and velocity means the same.it is measured in (m/s)
but..
speed doesn't have a direction and velocity has a direction
speed- scalar quantity
velocity- vector quantity

acceleration means the rate of change of speed thus it means ((m/s)/s)=(m/s2)

acceleration- vector quantity
