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 acceleration (g).

Front

What are the units for mass?

Back

Kilograms (kg) are the standard unit for mass.

Front

What are the units for weight?

Back

Newtons (N) are the standard unit for weight.

Front

What is gravitational acceleration 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 free fall?

Back

Free fall is the state when the only force acting on an object is gravity.

Front

What is the gravitational strength on Venus if a 100 kg object weighs 90 N?

Back

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

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the relationship between mass and weight?

Back

Weight is directly proportional to mass; as mass increases, weight increases.
