Types of Inertia

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.

Study the following scenarios and identify what type of inertia tends to resist the change.

1. When the bus suddenly starts, the passenger on the bus tends to fall backwards.

2. When a passenger jumps out of moving bus, he falls down.

3. A cyclist riding on a level road does not come to rest immediately even he stops pedalling.

1. All are due to the inertia of rest.

2. Only 1 and 3 are due to the inertia of rest and 2 is due to the inertia of motion.

3. Only 1 is due to the inertia of rest and others are due to the inertia of motion.

4. Only 1 is due to the inertia of motion and others are due to the inertia of rest.

Q.

An athlete can take a longer jump if he comes running from a distance. Identify the type of inertia.

1. Inertia of direction

2. Inertia of rest

3. Inertia of position

4. Inertia of motion

Q. An athlete can take a longer jump if he comes running from a large distance. Identify the type of inertia at the time of jump.

1. Static Inertia
2. Dynamic Inertia
3. Both static and dynamic inertia at the same time
4. No inertia at the time of jump

Q.

An athlete can take a longer jump if he comes running from a distance. Identify the type of inertia.

1. Inertia of direction

2. Inertia of rest

3. Inertia of position

4. Inertia of motion

Q. A person jumping out of a moving bus tends to move in the direction of the bus. This is due to;

1. Static Inertia
2. Dynamic Inertia
3. Frictional force
4. Gravitational force

Q. A person jumping out of a moving bus tends to roll forward, in the direction of the bus. This is due to the:

1. Inertia of rest
2. Inertia of motion
3. Inertia of direction
4. Force of gravity

Q. A person jumping out of a moving bus tends to move in the direction of the bus due to

1. static inertia
2. dynamic inertia
3. gravitational force
