P4 Revision 0.0 / 5 ? BiologyGCSEOCR Created by: Chris JenkinsCreated on: 04-05-13 10:40 What is the equation for describing motion graphs? Change of speed / time taken for change. 1 of 22 What is force measured? Newtons (N). 2 of 22 Momentum = ? Mass (kg) x velocity (m/s). 3 of 22 What is momentum measured in? Kgm/s. 4 of 22 Change in momentum = ? Resultant force x time taken. 5 of 22 What is Newton's first law of motion? A body remains stationary or at a constant speed unless acted on by a resultant force. 6 of 22 What is Newton's second law of motion? Force = Mass x Acceleration. 7 of 22 What is Newton's third law of motion? Every reaction has an equal and opposite reaction. 8 of 22 How do you get a car out of a muddy field? Slowly accelerate so that the tyres can grip, then speed up lots. 9 of 22 Decrease in GPE = ? Increase in KE. 10 of 22 What will happen to a well oiled trolley if you keep pushing it? It will speed up. 11 of 22 1kg on Earth = ? 10N. 12 of 22 Weight = ? Mass x Gravity. 13 of 22 1kg on moon = ? 1.6N. 14 of 22 Speed (km/h) = ? Distance (km) / Time (h). 15 of 22 Acceleration = ? Change in velocity (m/s) / Time taken (s). 16 of 22 Work done by a force = ? Force x Distance Moved. 17 of 22 Work done = ? Energy Transferred. 18 of 22 Page 129 in Physics textbook? . 19 of 22 Energy is measured in? Joules. 20 of 22 KE = ? 0.5 x mass x v(squared). 21 of 22 Page 116 - 118 graphs? . 22 of 22
