In everyday life, the terms mass and weight are interchangeable. However, in physics mass and weight do not mean the same.

The force of gravity acting on an object is called...?

Its mass

Its weight

Its downforce

Mass is?

A measure of the amount of matter in an object

A force

Measured in newtons, N

A force of 1N is approximately the force needed to lift?

A sugar cube

An apple

A car

What is the gravitational field strength of Earth?

10 N/kg

1.6 N/kg

25 N/kg

How is weight calculated?

Weight = mass × gravitational field strength

Weight = gravitational field strength ÷ mass

Weight = mass ÷ gravitational field strength

What is the weight of a 40 kg child on Earth (g = 10 N/kg)?

40 kg

4 N

400 N

A car has a weight of 10,000 N. What is the mass of the car on Earth (g = 10 N/kg)?

1000 kg

1000 N

10,000 kg

What is a newton meter?

A unit for speed

A calibrated spring-balance

A unit for weight

Which of the following statements is false?

Weight is a vector quantity

Weight is measured in newtons, N

The weight of an object is the same on the Earth and the moon

A girl has a weight of 88 N on the moon, where g = 1.6 N/kg. What is her mass?
