Question

differ between velocity and speed

Answer 1

Hello

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement.

Speed is scalar

velocity is vector

Answer 2

SPEED

• Speed is nothing but the distance travelled by an object per unit of time.
• Speed is a scalar quantity because speed only depends upon the magnitude not the direction of motion of the object.
• Speed is always positive because it doesn't depend on the direction of motion of the object.
• If an object started moving then the speed can never be zero because once object moves then distance is covered which cannot be zero.

VELOCITY

• Velocity is displacement of object per unit of time.

• Velocity  is vector quantity because it depends on the magnitude as well as the direction of motion of object.

• Velocity may be positive and negative as it depends on the direction in which object moves.

• If an object started moving then velocity may be zero if the displacement of the object is zero.
