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