Question

Distinguish between speed and velocity ?​

Answer 1

Explanation:

Speed is the distance travelled per unit time irrespective of direction, so only magnitude is of importance, and that it is a scalar quantity. Speed can be calculated using the formula:

d

i

s

tan

c

e

t

i

m

e

Velocity is the distance travelled per unit time in a specific direction, so both magnitude and direction are important, and that it is a vector quantity. Velocity can be calculated using the formula:

d

i

s

p

l

a

c

e

m

e

n

t

t

i

m

e

Acceleration is the rate of change of velocity of an object. Magnitude and direction are both considered, so it is a vector quantity. Acceleration can be calculated using the formula:

a

=

v

−

u

t

, where

a

=acceleration,

v

=final velocity,

u

=initial velocity and

t

=time.

Answer 2

The reason is simple speed is the time rate which an object is moving along a path while velocity is the rate and direction of an object movement

Put another way speed is a scaler value

while velocity is vector
