Mass & Weight

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, measured in kilograms (kg). Weight is the force of gravity acting on that mass, measured in newtons (N).

Front

How is mass measured?

Back

Mass is measured using a balance.

Front

What is the unit of weight?

Back

The unit of weight is the Newton (N).

Front

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

Back

The mass remains 50 kg on Jupiter.

Front

What happens to weight as you move away from Earth?

Back

Weight decreases as you move away from Earth due to reduced gravitational pull.

Front

What is the formula to calculate weight?

Back

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

Front

What is gravitational acceleration on Earth?

Back

Gravitational acceleration on Earth is approximately 9.8 m/s².

Front

If an object weighs 490 N on Earth, what would it weigh on Jupiter?

Back

It would weigh approximately 980 N on Jupiter.

Front

What tool do you use to measure mass?

Back

You use a balance to measure mass.

Front

Does mass change when you go to the Moon?

Back

No, mass does not change when you go to the Moon.
