Numeracy: Newton's Second Law Simulation

Activity

Stage 5 students will use this simulation as a basis for calculations to invesigate Newton's Second law of Motion: F = m x a. Students will use the simulation to compare the effects of different forces on the same mass and the impact this has on the acceleration of the skateboard. Using the equation, students will be able to understand the relationship from a numerical point of view. More advanced students who are able to complete the task faster can then repeat the calculations, changing the mass and making predictions about its effect using the equation. Students who struggle with mathematical concepts will be able to do the work without the calculations, visualising Newton's second law.
