Explain: Velocity-time graphs A web page with a number of questions at the bottom to test learners on the interpretation of velocity-time graphs. Extend: Game graphs A simple game in which players have to move a slider to match a distance/time graph; attempts are scored. Evaluate: SAMs question J259-01 Question 13 Link to delivery guide Link to SAM 7 (1hr for separate and combined) P4.2.11 explain that inertial mass is a measure of how difficult it is to change the velocity of an object and that it is defined as the ratio of force over acceleration Engage: What is inertia? Explore: Practical activity 1 “What effect does mass have on the inertia of an object?” Problem: You are given a piece of card, a beaker, and three objects that have different masses (low, medium, high). You will place the card on top of the beaker and the object on top of the card. Try to remove the card and get the object to fall into the beaker. Will the mass of the object have an effect if it will land in the beaker? Explain: Practical activity 2 Extend: Quick quiz Evaluate: Get pupils to add to their newton’s laws fact sheet. What have they learnt today? What is inertia? Pupils to write relevant information and start their fact sheet. Link to delivery guide
