Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

Which object has more inertia: a small rock or a large boulder?

Back

A large boulder has more inertia because it has more mass.

Front

What is mass?

Back

Mass is the amount of matter in an object, typically measured in kilograms or pounds.

Front

How does weight differ from mass?

Back

Weight is the force exerted by gravity on an object, while mass is the amount of matter in the object.

Front

What happens to the force of gravity if the distance between two objects increases?

Back

The force of gravity gets smaller as the distance between the objects increases.

Front

What is the normal force?

Back

The normal force is the support force exerted upon an object that is in contact with a surface.

Front

When does the normal force exceed gravitational force?

Back

The normal force exceeds gravitational force when an object accelerates upwards, such as in an elevator.

Front

What is the formula for calculating weight?

Back

Weight = mass × gravitational acceleration (W = m × g).

Front

What is gravitational acceleration on Earth?

Back

Gravitational acceleration on Earth is approximately 9.81 m/s².

Front

What is the relationship between mass and weight on different celestial bodies?

Back

Mass remains constant, but weight changes depending on the gravitational pull of the celestial body.
