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 exerted by gravity on that mass, measured in newtons (N).

Front

What unit is used to measure weight?

Back

Newton (N) is the unit used to measure weight.

Front

What unit is used to measure mass?

Back

Kilogram (kg) is the unit used to measure mass.

Front

Why do objects weigh less on the Moon?

Back

Objects weigh less on the Moon because the Moon has less gravitational pull compared to Earth.

Front

What is gravitational pull?

Back

Gravitational pull is the force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

If an object has a mass of 10 kg on Earth, what is its weight? (Use g = 9.8 m/s²)

Back

Weight = mass × gravity = 10 kg × 9.8 m/s² = 98 N.

Front

What happens to your weight if you travel to Jupiter?

Back

Your weight would increase on Jupiter because it has a stronger gravitational pull than Earth.

Front

What is the formula to calculate weight?

Back

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

Front

What is the gravitational acceleration on Earth?

Back

The gravitational acceleration on Earth is approximately 9.8 m/s².

Front

How does mass affect weight?

Back

The more mass an object has, the greater its weight will be, assuming the gravitational pull is constant.
