1 Speed in a specified direction. 2 A flat line on this type of graph means stationary. 3 Measured in m/s/s (m/s2) or (ms-2). 4 Change in velocity Time taken 5 ‘Amount of stuff’, this remains constant even if you’re on the moon! 6 The size difference between 2 opposite forces. This determines any changes in movement. 7 The size of a resultant force required to produce no change in movement. 8 The maximum speed an object can reach. This can be changed by producing a non-zero resultant force (often by increasing / reducing the resistance). 9 This is affected by: Your speed Tiredness, distractions, poor visibility, alcohol, carelessness, drugs, answering your phone etc. 10 The higher you are, the more you have. Mass x gravity x height 11 The faster you go, the more you have. ½ x mass x velocity2 12 Kids Hate Learning GCSE Energy Names. 13 Energy cannot be created or destroyed, only transferred into other types. 14 The extension of an elastic object in relation to the force applied (until the elastic limit of proportionality is reached). 15 Also known as Energy Transferred. Measured in J or Nm 16 Momentum before compared with momentum after. 17 Opposite charges _______. 18 Voltmeters are connected like this so they can measure the difference in energy across a component. 19 This has a constant current, wherever it is measured. 20 The average time for the number of nuclei in a radioactive sample to halve .
