Mass vs Weight

Front

What is the definition of mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms.

Front

What is the definition of weight?

Back

Weight is the force exerted by gravity on an object, calculated as mass times the acceleration due to gravity (W = mg).

Front

How do you find the mass of a liquid?

Back

Measure the mass of an empty container, pour the liquid into it, and then measure both; finally subtract the mass of the empty container.

Front

Which unit is used to measure mass?

Back

Kilogram (kg) is the standard unit of mass.

Front

What does it mean when we say an object's mass never changes?

Back

It means that the amount of matter in the object remains constant regardless of its location.

Front

What is matter?

Back

Matter is anything that has mass and takes up space.

Front

What is the relationship between mass and weight?

Back

Weight is dependent on mass and the gravitational pull; mass remains constant while weight can change with gravity.

Front

What is the formula to calculate weight?

Back

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

Front

Can mass be measured in pounds?

Back

Yes, pounds can be used to measure mass, but the standard SI unit is kilograms.

Front

What happens to an object's weight on the Moon compared to Earth?

Back

An object's weight is less on the Moon due to the Moon's weaker gravitational pull.
