6.5.1.4 AQA Resultant forces

What is a single force that has the same effect as all the original forces acting together called?

• Net force

• Gravitational force

• Resultant force

• Frictional force

What should students be able to calculate regarding two forces that act in a straight line?

• The sum of the forces

• The resultant of the forces

• The difference of the forces

• The product of the forces

What type of diagrams should students use to describe examples of forces acting on an isolated object? (HT)

• Vector diagrams

• Free body diagrams

• Circuit diagrams

• Flowcharts

What is the resultant force when balanced forces act on an object?

• Maximum

• Zero

• Minimum

• Infinite

What can a single force be resolved into when acting at right angles to each other? (HT)

• Two components

• Three components

• Four components

• Five components

What should students be able to use to illustrate the resolution of forces? (HT)

• Scale drawings

• Bar graphs

• Pie charts

• Histograms

What is the purpose of using vector diagrams in the context of forces? (HT)

• To measure temperature

• To illustrate resolution of forces

• To calculate speed

• To determine mass

What should students determine using vector diagrams regarding two forces?

• Speed and velocity

• Magnitude and direction

• Mass and weight

• Temperature and pressure

What is the effect of two component forces acting at right angles to each other? (HT)

• They cancel each other out

• They have the same effect as the single force

• They increase the object's mass

• They decrease the object's speed

What should students describe using free body diagrams? (HT)

• Examples of forces acting on a system

• Examples of chemical reactions

• Examples of electrical circuits
