mass vs weight

Front

What is 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 weight?

Back

Weight is the force of gravity acting on an object, calculated as the mass of the object multiplied by the acceleration due to gravity (W = m * g).

Front

How do you calculate weight on Earth?

Back

Weight (W) = Mass (m) × Acceleration due to gravity (g). On Earth, g is approximately 9.8 m/s².

Front

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

Back

Weight = 10 kg × 9.8 m/s² = 98 N.

Front

What happens to mass in different gravitational fields?

Back

Mass remains constant regardless of the gravitational field; it does not change whether on Earth, the Moon, or in space.

Front

What happens to weight in different gravitational fields?

Back

Weight changes depending on the strength of the gravitational field; it is less on the Moon than on Earth.

Front

What is the relationship between mass and weight?

Back

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

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law states that Force (F) equals mass (m) times acceleration (a), or F = m * a.

Front

If a force of 50 N is applied to a 5 kg object, what is its acceleration?

Back

Acceleration = Force / Mass = 50 N / 5 kg = 10 m/s².

Front

What is the unit of weight?

Back

The unit of weight is the Newton (N), which is equivalent to kg·m/s².
