Hooke’s law 0.0 / 5 ? PhysicsForcesGCSEOCR Created by: millieb0168Created on: 09-04-21 13:56 What is the equation for extension? Extension= new length- original length 1 of 15 How would you make sure this experiment is carried out safely? By Standing up and wearing safety goggles 2 of 15 What equipment is needed for this practical? A clamp and clamp stand, a spring, ruler, pointer and masses 3 of 15 What is the first step in this practical? Hang the spring from the clamp then measure the spring length. 4 of 15 How do you know if the spring has obeyed Hooke’s law? The line of best fit will be straight. 5 of 15 What should be on the x and y axis Force against extension 6 of 15 What do you do after each mass is added? Measure the length of the spring. 7 of 15 What do you do before you add the masses? Weigh the masses 8 of 15 What should happen to you graph if you load enough masses? The graph should start to curve 9 of 15 What could happen if you don’t wear safety goggles? If the spring snaps, you could injure ur eyes 10 of 15 Why must you stand up when doing this practical? So you can move from falling weight 11 of 15 What should the gradient equal if it obeys Hooke’s law? Gradient= spring constant 12 of 15 What is the second step in this practical? Weigh your masses and add them one at a time 13 of 15 Why should you use a pointer? To help measure the length of the spring. 14 of 15 What is the third step in this practical? After each mass, measure the length of the spring. 15 of 15
