By the end of the lesson, you should be able to:

• Categorise everyday forces as ‘contact’ or ‘non-contact’

• Interpret force diagrams used to illustrate problems involving gravity

• Describe what ‘interaction pair’ means

Basics

By the end of the lesson, you should be able to:

• Describe the difference between balanced & unbalanced forces, and what 'equilibrium' means

• Calculate resultant forces

• Explain why the speed or direction of an object can change using force arrows

Basics

By the end of the lesson, you should be able to:

• Calculate speed, distance or time using the speed equation

• Describe & explain how a moving object appears to a stationary observer

• Describe & explain how a moving object appears to a moving observer

Basics

By the end of the lesson, you should be able to:

• Accurately plot data on a distance-time graph

• Interpret distance-time graphs

• Calculate speed from a distance-time graph, and convert between units

Basics

By the end of the lesson, you should be able to:

• Describe the difference between mass and weight

• Describe how gravity due to an object changes if the mass or the distance from the object changes

• Use the formula weight = mass x g to work out the weight of an object on different planets and compare it to the weight on Earth
