A.2 - 4 - Mass v Weight

What is mass?

• The force of gravity acting on an object.

• The amount of matter in an object.

• A vector quantity.

• Measured in Newtons.

How is weight defined and measured?

• The amount of matter in an object, measured in kilograms.

• The force of gravity acting on an object, measured in kilograms.

• The force of gravity acting on an object, measured in Newtons.

• The amount of matter in an object, measured in Newtons.

Which equation correctly represents how to calculate the weight of an object?

• Weight = mass / acceleration

• Weight = mass + acceleration

• Weight = mass * acceleration of gravity (g)

• Weight = acceleration of gravity (g) / mass

What happens to an object's mass and weight when it is moved from Earth to deep space where there is no gravity?

• Both mass and weight remain the same.

• Mass remains the same, but weight becomes zero.

• Weight remains the same, but mass becomes zero.

• Both mass and weight become zero.
