Mass vs. 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 is the formula to calculate weight?

Back

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

Front

What is gravitational strength?

Back

Gravitational strength is the force of gravity acting on an object per unit mass, measured in newtons per kilogram (N/kg).

Front

What is the gravitational strength on Earth?

Back

Approximately 9.8 N/kg.

Front

If an object has a mass of 10 kg, what is its weight on Earth?

Back

Weight = 10 kg × 9.8 N/kg = 98 N.

Front

What is the unit of measurement for weight?

Back

The unit of measurement for weight is newtons (N).

Front

What is gravity?

Back

Gravity is the attractive force between any two objects that depends on their masses and the distance between them.

Front

What is force?

Back

Force is a push or pull action that can cause an object to move, stop, or change direction.

Front

How does mass affect weight?

Back

As mass increases, weight increases, assuming gravitational strength remains constant.

Front

What happens to weight if you go to a planet with lower gravitational strength?

Back

Weight decreases because weight is directly proportional to gravitational strength.
