What does scalar quantity mean?

• A measurement that must be given as a rounded decimal

• A measurement that can be either positive or negative

• A measurement that has a magnitude only

• A measurement that has a magnitude and direction

Which of the following is NOT a scalar quantity?

• Mass

• Speed

• Scale

• Temperature

Which of the following is a scalar quantity?

• Momentum

• Distance

• Acceleration

• Force

What is the difference between a scalar and a vector?

• A vector is larger than a scalar

• A vector is a direction

• A scalar has direction

• A vector has direction and magnitude

Which of the following is an example of non-contact forces?

• Friction

• Gravitational force

• Tension

• Air resistance

Which of the following statements is completely true?

• Distance is a vector quantity

• Velocity is distance over time

• Acceleration is speed over time

• Velocity is displacement over time

If a velocity-time graph consists of one diagonal line in the downwards direction, which of the following statements about the motion are true?

• The object is going faster

• The object is decelerating at a constant rate

• The object is decelerating at a non-constant rate

• The object is travelling at a constant velocity

• The object is traveling at a non-constant velocity

What are the units of measurement of weight?

• pounds

• tonnes

• newtons

• kilograms

Answer explanation

Weight is a force, so it is measured in newtons – like all forces.

The more mass an object has, the greater its weight.

Which of these is the correct definition of inertia?

• How difficult it is to change an object's motion

• The object's weight

• The gravitational field strength

• The object's mass

Choose the correct equation for weight.

• weight = mass x gravitational field

  strength

• weight = weight x time

• weight = gravitational field

  strength x time

• weight = gravitational field

  strength x length
