Mass, Weight and "baby g"

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 weight change with location?

Back

Weight changes with location because gravitational field strength varies depending on where you are (e.g., Earth vs. Moon).

Front

What is 'baby g'?

Back

'Baby g' refers to the gravitational acceleration experienced on the Moon, which is about 1/6th that of Earth's gravitational acceleration.

Front

Is mass the same on the Moon as on Earth?

Back

Yes, mass remains the same regardless of location; a 45 kg girl has the same mass on the Moon as on Earth.

Front

What is the relationship between mass and weight?

Back

Mass and weight are related; weight is the gravitational force acting on mass. Weight = mass x gravitational acceleration.

Front

What happens to an object's weight if it is taken to a location with a stronger gravitational field?

Back

The object's weight increases because weight is directly proportional to gravitational field strength.

Front

What is the formula to calculate weight?

Back

Weight (W) = Mass (m) x Gravitational Acceleration (g).

Front

What is gravitational acceleration on Earth?

Back

Gravitational acceleration on Earth is approximately 9.81 m/s².

Front

What is gravitational acceleration on the Moon?

Back

Gravitational acceleration on the Moon is approximately 1.62 m/s².
