7_01_Time and Motion

The distance moved by an object in a unit time is called

• acceleration

• speed

• motion

• displacement

the S.I unit of speed is

• cm/s

• cm

• m

• m/s

Speed =

• distance covered

• distance covered X time taken

• distance covered / time taken

• time taken / distance covered

Motion which repeats itself in a regular intervals of time is called ..............

• Linear motion

• circular motion

• periodic motion

• irregular motion

Motion of objects can be presented in pictorial form by their...............

• distance- speed graph

• distance-time graph

• time-time graph

• speed- distance graph

Which of the following graph represents body is at rest position?

• 
• 
• 
• 

Observe the figure.

The time period of a simple pendulum is the time taken by it to travel from

• A to B and back to A

• O to A, A to B and B to A

• B to A, A to B and B to O

• A to B

Which of the following is used to measure the distance traveled by a vehicle?

• Speedometer

• hydrometer

• odometer

• manometer

When a body covers unequal distances in equal intervals of time then it is said to be in ............. motion

• uniform

• non uniform

• periodic

• vibratory

The given graph represents

• Speed of A < Speed of B

• Speed of B < Speed of A

• Speed of A = Speed of B

• body is at rest
