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). Weight is the force exerted by gravity on that mass, measured in newtons (N).

Front

Which has more mass, Earth or the Moon?

Back

Earth has more mass than the Moon.

Front

As an object's mass increases, its gravitational pull will ____________.

Back

increase.

Front

What is the scientific unit of weight?

Back

The scientific unit of weight is the newton (N).

Front

If an object has more mass, then it will ____________.

Back

weigh more.

Front

What is the scientific unit for mass?

Back

The scientific unit for mass is the kilogram (kg).

Front

How does gravity affect weight?

Back

Weight is directly proportional to the gravitational force acting on an object; more gravity means more weight.

Front

Can an object have mass but no weight?

Back

No, an object must be in a gravitational field to have weight, but it can have mass regardless of location.

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 9.81 m/s².
