Calculating weight and mass

Front

What is the formula to calculate weight?

Back

Weight = Mass x Acceleration due to gravity

Front

What is the unit of weight in the International System of Units (SI)?

Back

Newton (N)

Front

What is the difference between mass and weight?

Back

Mass is how much matter is in an object, and weight is the gravitational pull on that object.

Front

If an object has a mass of 10 kg, what is its weight on Earth? (g = 9.8 m/s²)

Back

Weight = 10 kg x 9.8 m/s² = 98 N

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.8 m/s²

Front

How does weight change on different planets?

Back

Weight changes depending on the gravitational pull of the planet, but mass remains constant.

Front

If an object weighs 490 N on Earth, what is its mass? (g = 9.8 m/s²)

Back

Mass = Weight / g = 490 N / 9.8 m/s² = 50 kg

Front

What is the weight of a 50 kg object on Jupiter? (g ≈ 24.79 m/s²)

Back

Weight = Mass x g = 50 kg x 24.79 m/s² = 1239.5 N

Front

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

Back

The mass remains the same regardless of location.

Front

What is the relationship between force, mass, and acceleration?

Back

Force = Mass x Acceleration (Newton's Second Law)
