Question

difference between speed and velocity​

Answer 1

SPEED

• Speed is the ratio of distance to time.

• It is a scalar quantity.

• It has magnitude only. It has no direction.

• The value of speed can be either zero or positive.

• Speed can not be negative.

• The average speed over a given period can never be zero.

• Speed of the particle in uniform circular motion is constant since it is independent of the direction.

v = d/t

where

v is the speed

d is the distance

t is the time

VELOCITY

• It is the rate of change of displacement.

• It is a vector quantity.

• It has both magnitude and direction.

• Its value can be zero or negative or positive.

• The average velocity over a given period be zero, if the displacement is zero.

• In uniform circular motion, velocity changes at every point, since the direction is changing.

v = s/t

where

v is the velocity

s is the displacement

t is the time.

Answer 2

Answer:

➤ Different between speed and velocity are as follows :-

✪ Speed :-

• The rate at which an object cover at a certain distance is known as speed.
• Speed is a scaler quantity.
• Speed is measured in m/s.
• Speed ascertains how fast a body moves.
• Formula for speed :- Speed = Distance travelled / Time taken.

✪ Velocity :-

• The rate at which an object changes position in an certain direction is known as velocity.
• Velocity is a vector quantity.
• Velocity is measured in m/s.
• Velocity ascertains the object's speed and the direction its takes while moving.
• Formula for velocity :- Velocity = Displacement / Time taken.
