Mass vs. Weight

Front

What is the definition of mass?

Back

Mass is the amount of matter in an object, typically measured in kilograms (kg). It does not change regardless of location.

Front

What is the definition of weight?

Back

Weight is the force exerted by gravity on an object, calculated as the product of mass and gravitational acceleration (W = m * g). It is measured in newtons (N).

Front

How does gravity affect weight?

Back

Weight is directly affected by gravity; as gravitational pull increases, weight increases, and vice versa.

Front

What is the formula to calculate weight?

Back

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

Front

If an object has a mass of 10 kg on Earth, what is its weight? (g = 9.81 m/s²)

Back

Weight = 10 kg × 9.81 m/s² = 98.1 N.

Front

What is the gravitational pull on Mercury?

Back

The gravitational pull on Mercury is approximately 3.59 m/s².

Front

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

Back

The mass of the object remains the same regardless of its location, including on the Moon.

Front

What is the gravitational strength of Venus if a 100 kg person weighs 90 N?

Back

Gravitational strength = Weight / Mass = 90 N / 100 kg = 0.9 N/kg.

Front

What is the relationship between mass and weight?

Back

Mass and weight are directly proportional; as mass increases, weight increases if gravity remains constant.

Front

What is the difference between mass and weight?

Back

Mass is a measure of matter, while weight is the force of gravity acting on that mass.
