Inertia-1

The video explains inertia, a principle stating that objects at rest stay at rest and objects in motion stay in motion unless acted upon by a force. It provides examples like books on a table and flowing water. The video discusses how inertia is related to an object's mass, with larger objects having more inertia. It also highlights the importance of inertia in safety, such as the use of seat belts.

What is an example of inertia in everyday life?

• A book resting on a table

• A bird flying

• A car accelerating

• A person running

What is required to change the motion of an object?

• A force

• Space

• Energy

• Time

Why do billiard balls continue to move after being hit?

• Due to air resistance

• Because of friction

• Due to inertia

• Because of gravity

How does the mass of an object affect its inertia?

• Less mass means more inertia

• Mass does not affect inertia

• More mass means less inertia

• More mass means more inertia

Why is it important to wear seat belts in a moving vehicle?

• To protect against inertia

• To increase speed

• To reduce inertia

• To prevent motion
