Hooke’s law 0.0 / 5 ? PhysicsForcesGCSEOCR Created by: millieb0168Created on: 09-04-21 14:22 What is the equation for extension? Extension=new length- original length 1 of 14 How would you perform this practical safely? By standing up and wearing safety goggles 2 of 14 What equipment is needed for this practical? A clamp and clamp stand, a spring, masses, ruler and pointer 3 of 14 What is the first step in this practical? Hang the spring from the clamps then measure the springs length 4 of 14 What should be on the X and Y axis of the graph? Force against extension 5 of 14 How do you know if hooks law has been obeyed? The line of best fit will be straight 6 of 14 What is step two of this practical? Why your Mrs and add them one at a time 7 of 14 What will the gradient equal if hooks law is obeyed? Gradient = spring constant 8 of 14 What could happen if you don’t wear safety goggles? The spring could snap and injure your eye 9 of 14 What is step three of this practical? After each mass is added, measure the length of the spring 10 of 14 What will happen to the graph if enough masses have been added? The graph will begin to curve 11 of 14 Why is it important to stand up when doing this practical? So you can move from falling weights 12 of 14 Why do you add multiple masses? So the force on the spring increases 13 of 14 After each mass is added what do you do? Measure the length of the spring 14 of 14
