Calculating mass and weight

What is the formula for calculating mass?

• mass = length x width x height

• The formula for calculating mass is mass = density x volume

• mass = force x acceleration

• mass = weight x volume

What is the formula for calculating weight?

• Weight = Mass + Acceleration due to gravity

• The formula for calculating weight is: Weight = Mass x Acceleration due to gravity

• Weight = Mass - Acceleration due to gravity

• Weight = Mass / Acceleration due to gravity

What is the difference between mass and weight?

• Mass is the force exerted on an object due to gravity, while weight is the amount of matter in an object

• Mass is measured in pounds, while weight is measured in kilograms

• Mass is the amount of matter in an object, while weight is the force exerted on an object due to gravity.

• Mass and weight are the same thing

If an object has a mass of 5 kg, what is its weight on Earth? (Take g = 9.8 m/s^2)

• 0.5 N

• 98 N

• 5 N

• 49 N

If an object has a weight of 50 N on Earth, what is its mass? (Take g = 9.8 m/s^2)

• The mass of the object is 5.1 kg.

• The mass of the object is 10 kg.

• The mass of the object is 50 kg.

• The mass of the object is 100 kg.

What is the unit of mass?

• The unit of mass is kilogram (kg).

• The unit of mass is second (s).

• The unit of mass is liter (L).

• The unit of mass is meter (m).

What is the unit of weight?

• The unit of weight is 'liter'

• The unit of weight is 'inch'

• The unit of weight is 'meter'

• The unit of weight is 'pound' in the imperial system and 'kilogram' in the metric system.

How does gravity affect mass and weight on different planets?

• Gravity affects mass by increasing on different planets, but weight remains constant.

• Gravity affects mass by decreasing on different planets, and weight also decreases.

• Gravity affects mass by remaining constant, but weight changes depending on the gravitational pull of the planet. Weight is the force of gravity acting on an object's mass.

• Gravity affects mass by decreasing on different planets, but weight remains constant.

Explain the concept of gravitational force.

• Gravitational force only affects objects on the Earth's surface.

• Gravitational force is the force of repulsion between two objects with mass.

• Gravitational force is the force of attraction between two objects with mass. It is responsible for keeping planets in orbit around the sun and objects on the Earth's surface.

• Gravitational force is not related to the mass of the objects.

Why is it easier to lift objects on the moon compared to Earth?

• It is easier to lift objects on the moon compared to Earth because the moon has denser atmosphere.

• It is easier to lift objects on the moon compared to Earth because the moon has stronger gravity.

• It is easier to lift objects on the moon compared to Earth because the moon has weaker gravity.

• It is easier to lift objects on the moon compared to Earth because the moon has no gravity.
