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

Front

How does mass change when moving to a different planet?

Back

Mass remains the same regardless of the planet or gravitational force acting on it.

Front

How does weight change when moving to a different planet?

Back

Weight changes depending on the gravitational pull of the planet. It is calculated using the formula W = m * g.

Front

What is the relationship between mass and weight?

Back

Mass and weight are directly proportional; as mass increases, weight increases, assuming constant gravitational acceleration.

Front

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

Back

Weight = mass * gravity = 10 kg * 9.8 m/s² = 98 N.

Front

What happens to the weight of an object if the gravitational pull is halved?

Back

The weight of the object will also be halved, as weight is directly proportional to gravitational pull.

Front

What is the formula to calculate weight?

Back

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

Front

If a squirrel weighs 4.9 N, what is its mass?

Back

Mass = Weight / g = 4.9 N / 9.8 m/s² = 0.5 kg.

Front

What is the gravitational acceleration on Earth?

Back

The gravitational acceleration on Earth is approximately 9.8 m/s².
