Question

`{:( "Column A"," ColumnB"),(A. "Non- uniform motion","a. To measure speed of the vehicle"),(B."Oscillatory motion","b. Uniform motion"),(C."Mean position" , "c. A criket ball that rolls over ground"),(D."Speedometer","d.The needle of sewing machine that moves up and down"),(E."Constant speed","e. Freely suspended pendulum at rest"),(F. "Acceleration","f".("Total change in velocity")/("Total time taken for change")):}`

Answer 1

Correct Answer - 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.
