Question

What is diffrence between speed , velocity and accleration?

Answer 1

speed is the rate of motion, or the rate of change of position. It is expressed as distance moved (d) per unit of time(t). Speed is a scalar quantity with dimensions distance/time. Speed is measured in the same physical units of measurement as velocity, but does not contain an element of direction. Speed is thus the magnitude component of velocity. Velocity contains both the magnitude and direction components.

acceleration is defined as the rate of change of velocity. It is thus a vector quantity with dimension length/time². In SI units, acceleration is measured in meters/second².

Answer 2

Speed:Distance travelled per unit time is Called speed.

Velocity: Distance travelled per time in a given direction is Called velocity .

Acceleration : Only if the body moves on a single straight line Path along the same direction .


I hope this answer is right
