(a) move backward
(b) move forward
(c) be unaffected
(d) rise upwards

Q.

How to measure the inertia of an object?

Q.

What is meant by the statement 'rest and motion are relative terms?' Give example to show it.

Q.

The inertia of a moving object depends on ___.

1. speed of the object.

2. force on the object.

3. mass of the object.

4. shape of the object.

Q.

What is the difference between friction and inertia? Are they same in some aspect?

Q.

An athlete runs some distance before taking a long jump. This is because

1. his body warms up.

2. his potential energy increases.

3. he loves running.

4. the run before jump helps him take a longer jump due to inertia of motion.

Q.

Why does a coin placed on a card, drop into the tumbler when the card is rapidly flicked with the finger?

Q. When a car at high speed makes a sharp turn, the driver in the car tends to get thrown in the direction opposite to that of the turn. This is due to which property?

1. Inertia of motion
2. Inertia of force
3. Inertia of rest
4. Inertia of direction

Q. Why do we fall sideways when the bus takes a sharp turn?

Q.

When a train suddenly starts moving forward, the passenger standing in the compartment tends to fall back is an example of inertia of ___ .

Q.

Give two examples to show that greater the mass, greater is the inertia of the body.

Q.

An athlete runs some distance before a long jump because

a) it helps him to apply large force

b) by running force increase

c) he gains energy

d) to get large inertia of Motion

Q.

What is meant by body at rest and body at motion?

Q.

The inertia of an object tends to cause the object:

1. to increase its speed

2. to decrease its speed

3. to resist any change in its state of motion

4. to decelerate due to friction

Q. Explain giving an example that an object can be in motion as well as at rest at the same time.

Q. Why do train have buffers in between the comartments?

Q.

Assertion: An object can move with constant velocity if no net force acts on it.
Reason: No net force is needed to move an object with constant velocity.

3. Both A and R are true and R is the correct explanation of A.

4. Both A and R are true but R is not the correct explanation of A.

2. A lighter body has a larger inertia than a heavier body
3. Inertia of a body does not depend on its mass
4. Inertia is the ability of a body to change its state of rest or of uniform motion on its own
