Distinguish, compare and explain what is the difference between speed and velocity in physics.
Difference between speed and velocity
- Speed is the distance covered by the body per unit time. Velocity is the displacewteAt of the body per unit time.
- Speed is a scalar quantity. Velocity is a vector quantity.
- The average speed of a moving body can never be zero. The average velocity of a moving body can be zero when the displacement is zero.
- Speed gives an idea about the rapidity of motion of the body. Velocity gives an idea about rapidity as well as the position of the body in motion.
- The speed of a moving body can never be negative. The velocity of a moving body can be positive, negative or zero depending on point of reference.
- SI unit of both speed and the velocity is meter/sec.
