Mass and Weight

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, measured in kilograms (kg), while weight is the force exerted by gravity on that mass, measured in newtons (N).

Front

What does a balance scale measure?

Back

A balance scale measures mass.

Front

What is the formula for calculating weight?

Back

Weight = Mass x Gravity (W = m x g).

Front

If an object has a mass of 50 kg on Earth, what is its weight? (Use g = 9.8 m/s²)

Back

Weight = 50 kg x 9.8 m/s² = 490 N.

Front

What is the gravitational acceleration on the Moon?

Back

The gravitational acceleration on the Moon is approximately 1.6 m/s².

Front

If a child has a mass of 30 kg on Earth, what is their weight on Earth?

Back

Weight = 30 kg x 9.8 m/s² = 294 N.

Front

What happens to mass when an object is taken to the Moon?

Back

The mass remains the same regardless of location; it is still 30 kg.

Front

What is the best definition for mass?

Back

Mass is how much matter an object contains.

Front

If the mass of an object is 1000 kg on Earth, what is its mass on the Moon?

Back

1000 kg.

Front

Which model has greater gravitational attraction if both have the same mass?

Back

Both models have the same gravitational attraction.
