IB PHYSICS > PRACTICAL WORK > IB IA EXPERIMENTS [|IA criteria checklist.doc] - always a good idea to look at this before submitting your work. =PRACTICAL: MEASURE THE ENERGY STORED IN THE SPRING OF A DYNAMICS TROLLEY=

APPARATUS:
Dynamics trolleys, masses, motion sensor, logger pro

PROCEDURE:
Use on trolley to project another along a horizontal surface using the spring mechanism. Measure the maximum velocity achieved by the projected trolley using the motion sensor and logger pro. Add a mass to the projected trolley and repeat the velocity measurement. Record a number of values for v and the mass of the trolley. Remember to record uncertainties. Plot a graph of m agains v. Using your knowledge of physics and mathematics, manipulate the data to achieve a straight line graph. Use the gradient of the line to calculate the energy stored in the spring.

RESULTS:
If it doesn't work out, try these results:
