Compatible with the Philip Harris Linear Air Track B8H25339

• Key Stage 3 Physics - Motion & Forces: Speed and the quantitative relationship between average speed, distance and time (speed = distance ÷ time). Forces being needed to cause objects to stop or start moving, or to change their speed or direction of motion (qualitative only).
• Key Stage 4 Physics - Forces & Motion: Explain the vector-scalar distinction as it applies to displacement, velocity and speed. Relate linear motion as observed from one moving vehicle to its observation from another moving.  Make and interpret measurements of distances, times, speeds and accelerations,and represent these in graphical form. Recall Newton’s First Law and relate it to observations showing that forces can change direction of motion as well as its speed; identify and distinguish between these for forces which alter motion in everyday experience. Recall Newton’s Second Law and explain its status as the definition of inertial mass. Recall and apply Newton’s Third Law both to equilibrium situations and to collision interactions and relate it to the conservation of momentum in collisions. Explain that force is rate of momentum change and explain the dangers caused by large decelerations and the forces involved. Forces as vectors. Interpreting quantitatively graphs of distance, time, and speed. Estimating speeds and accelerations in everyday contexts.

Help your students explore and understand:

• Velocity and acceleration
• Newton's laws of motion
• Elastic and inelastic collisions
• Conservation of momentum in an ideal world, without the problem of friction - they can deal with that in later experiments!
