Forces in Motion and Performance Analysis

All | Design & Technology | Physics | Science | 11-16

Learning Objectives

  • Explain how we can use graphs of motion to describe a race and analyse performance.
  • Calculate distance using speed time data from a race boat

Skills Focus

  • Organising and plotting data, analysing data, distance calculation.

Lesson Description

Join INEOS TEAM UK engineers and learn how to analyse the data from a training run on board Britannia, the cutting edge 60mph America’s Cup sailing boat.

In this lesson we ask, “How do we make sure we get the best performance out of the boat?”

The resource includes a video introducing the importance of data and providing speed time data for students to analyse. A comprehensive editable teacher PowerPoint presentation including teaching notes and a student exercise in plotting and analysing speed time data.

Along with a look at how we can calculate distance from a speed time graph. Students then use their analysis skills to calculate the best strategy for the race team to adopt following the start of the race.

This lesson is one in a series of five exploring forces through practical investigations linked to the real-life exciting context of the British America’s Cup team. Each lesson focuses on a series of key questions and is aimed at the knowledge and skills requirements of KS3 science, it also has relevance for the numeracy content for both Engineering and Design Technology students at KS4.

Motion and Forces

Describing motion

  • Speed and the quantitative relationship between average speed, distance, and time (speed = distance ÷ time)
  • The representation of a journey on a distance-time graph


  • Forces as pushes or pulls, arising from the interaction between 2 objects
  • Using force arrows in diagrams, adding forces in 1 dimension, balanced and unbalanced forces
  • Moment as the turning effect of a force
  • Forces: associated with deforming objects; stretching and squashing – springs; with rubbing and friction between surfaces, with pushing things out of the way; resistance to motion of air and water
  • Forces measured in newtons, measurements of stretch or compression as force is changed

Pressure in fluids

  • Pressure in liquids, increasing with depth; upthrust effects, floating and sinking

Balanced forces

  • Opposing forces and equilibrium: weight held by stretched spring or supported on a compressed surface

Forces and motion

  • Forces being needed to cause objects to stop or start moving, or to change their speed or direction of motion (qualitative only)
  • Change depending on direction of force and its size

Forces: developing an understanding of how forces can change the shape or motion of an object and the forces acting on it and developing an understanding of the concept of buoyancy, force, and density.

Working scientifically

  • Through the content across all five lessons students will develop:

Scientific attitudes

  • Pay attention to objectivity and concern for accuracy, precision, repeatability and reproducibility
  • Evaluate risks

Experimental skills and investigations

  • Ask questions and develop a line of enquiry based on observations of the real world, alongside prior knowledge and experience
  • Make predictions using scientific knowledge and understanding
  • Select, plan, and carry out the most appropriate types of scientific enquiries to test predictions, including identifying independent, dependent, and control variables, where appropriate
  • Use appropriate techniques, apparatus, and materials during laboratory work, paying attention to health and safety
  • Make and record observations and measurements using a range of methods for different investigations, and evaluate the reliability of methods and suggest possible improvements

Analysis and evaluation  

  • Apply mathematical concepts and calculate results
  • Present observations and data using appropriate methods, including tables and graphs
  • Interpret observations and data, including identifying patterns and using observations, measurements and data to draw conclusions
  • Present reasoned explanations, including explaining data in relation to predictions and hypotheses
  • Evaluate data, showing awareness of potential sources of random and systematic error
  • Identify further questions arising from their results
