(b.) A bus decreases its speed from 50 km/hr to 60 km/hr in 5 seconds. Find the acceleration of
the bus.​

Answer 1

Answer:

SPEED

● Speed of the body is the travelled by if per unit time.

● It is a scalar quantity.

● It cannot be zero.

VELOCITY

● Velocity of a body is the distance travelled by it per unit time in a given direction.

● It is a vector quantity.

● It can be zero.

Answer 2

Answer:

Explanation:

difference between speed and velocity

speed:

1. It is the distance travelled by a body in unit time.

2. It is a scalar quantity.

3.it can be changed by changing the distance travelled by a body in a particular time.

4.It is always positive or zero but can never be negative.

velocity:

1.Velocity is the speed of an object moving in definite direction.

2.It is a vector quantity.

3.It can be changed by changing the speed of a body.

4.It may be positive, zero or negative sometimes.
