Mass and Weight

Front

What is mass?

Back

Mass is the amount of matter in an object, usually measured in grams or kilograms.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as mass times the acceleration due to gravity (W = m × g).

Front

How does mass change on different planets?

Back

Mass remains the same regardless of location; it does not change whether on Earth, the Moon, or any other planet.

Front

What happens to weight on the Moon compared to Earth?

Back

Weight is less on the Moon due to its weaker gravitational pull, but mass remains unchanged.

Front

What is the relationship between mass and gravitational force?

Back

As mass increases, the gravitational force between two objects also increases.

Front

What happens to gravitational force as distance increases?

Back

The gravitational force decreases as the distance between two objects increases.

Front

If an object has a mass of 50 kg on Earth, what is its mass on the Moon?

Back

50 kg (mass does not change).

Front

What is the formula for calculating weight?

Back

Weight (W) = Mass (m) × Gravitational acceleration (g).

Front

What is gravitational acceleration on Earth?

Back

Approximately 9.8 m/s².

Front

If Earth's mass was cut in half, what would happen to your mass?

Back

Nothing; mass is not affected by gravitational force.
