Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
A-c A cricket ball rolls over the ground , its speed decreases.
B-d The needle of sewing machine that moves uo and down is an example of oscillatory motoin.
C-e Mean position of a freely suspended pendulum is at that position where it stays at rest .
D-a Speedometer is used to measure the speed of the vehicle.
E-d A body moving with constant speed is said to be in uniform motion.
F-f The rate of change in velocity is called acceleration.
