Newton's Law of Inertia

Click on the flashcard to see the answer



What is another name for Newton's First Law of Motion?

The Law of Inertia.

What does Newton's Law of Inertia state about an object at rest?

An object at rest will stay at rest unless acted upon by an external force.

What does Newton's Law of Inertia say about an object in motion?

An object in motion will continue in motion at a constant velocity unless acted upon by an external force.

In the context of inertia, what is required to change the state of motion of an object?

An external force is required to change the state of motion.

How does mass relate to inertia?

The greater the mass of an object, the greater its inertia.

Give an example of inertia in everyday life.

A book resting on a table remains at rest until someone moves it.

What is meant by "constant velocity" in the context of inertial motion?

Constant velocity means moving in a straight line at a constant speed.

What role does friction play in Newton’s Law of Inertia?

Friction is an external force that can stop or slow down the motion of objects.

Why does a passenger lurch forward in a bus when it stops suddenly?

Due to inertia, the passenger tends to keep moving forward when the bus stops.

What will happen to a rolling ball in a vacuum according to the Law of Inertia?

It will keep rolling indefinitely because there are no external forces like friction.

How can one overcome inertia?

By applying a sufficient external force to change the object's state of motion.

In terms of inertia, why is it harder to push a filled shopping cart than an empty one?

A filled shopping cart has more mass and therefore more inertia.

How does seatbelt usage in cars relate to inertia?

Seatbelts provide an external force to stop the motion of passengers in case of sudden stops.

Why does a ball thrown in space continue to travel?

There is no external force in space to stop it, so it continues due to inertia.

Which of Newton's laws is the basis for the concept of equilibrium?

Newton's First Law of Motion, or the Law of Inertia, is the basis for equilibrium.

1. What is another name for Newton's First Law of Motion?

The Principle of Relativity.

The Law of Inertia.

The Law of Gravity.

The Law of Action.

2. What does Newton's Law of Inertia state about an object at rest?

It will start moving without any force.

It will move in circles until acted upon.

An object at rest will stay at rest unless acted upon by an external force.

It will vibrate until an external force is applied.

3. In the context of inertia, what is required to change the state of motion of an object?

A change in temperature.

Increased mass.

More inertia.

An external force is required to change the state of motion.

4. How does mass relate to inertia?

The greater the mass of an object, the greater its inertia.

Mass does not affect inertia.

Inertia increases as mass decreases.

Inertia is not related to mass.

5. What role does friction play in Newton’s Law of Inertia?

Friction is an external force that can stop or slow down the motion of objects.

Friction accelerates motion.

Friction is required to maintain motion.

Friction has no impact on inertia.

6. Why does a passenger lurch forward in a bus when it stops suddenly?

Because of gravitational pull.

Due to the air pressure inside the bus.

Due to inertia, the passenger tends to keep moving forward when the bus stops.

Because the bus applies a backward force on the passenger.

7. What will happen to a rolling ball in a vacuum according to the Law of Inertia?

It will come to a stop immediately.

It will keep rolling indefinitely because there are no external forces like friction.

It will slow down gradually.

It will change direction spontaneously.

8. How can one overcome inertia?

By applying a sufficient external force to change the object's state of motion.

By increasing the object's mass.

By reducing temperature.

By removing the object's mass.

9. In terms of inertia, why is it harder to push a filled shopping cart than an empty one?

Because the wheels are less smooth.

Because it's larger in size.

Because it has less friction with the ground.

A filled shopping cart has more mass and therefore more inertia.
