Question 1:
Give the meaning of inertia and provide two examples of inertia in our daily life.

Inertia is the natural tendency of an object to resist any change in its original state, whether being at rest or in motion.

Examples of inertia:
• Dry an umbrella by spinning it fast and stopping it suddenly.

• The driver is hurled forward when the brakes are applied suddenly.

Question 2:

The greater the mass, the greater the inertia.
