mass vs. weight

Front

What is mass?

Back

The amount of material in an object.

Front

What is weight?

Back

The force of gravity acting on an object.

Front

How is weight calculated?

Back

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

Front

What is the gravitational acceleration on Earth?

Back

Approximately 9.81 m/s².

Front

If an object has a mass of 10 kg, what is its weight on Earth?

Back

Weight = 10 kg × 9.81 m/s² = 98.1 N.

Front

Does mass change with location?

Back

No, mass remains constant regardless of location.

Front

Does weight change with location?

Back

Yes, weight varies depending on the gravitational field strength.

Front

Where is a person's weight greater, Earth or Moon?

Back

Earth.

Front

What happens to weight on Mars compared to Earth?

Back

Weight is less on Mars due to lower gravitational acceleration.

Front

What is the mass of an object that weighs 196.2 N on Earth?

Back

Mass = Weight / g = 196.2 N / 9.81 m/s² ≈ 20 kg.
