Measuring eneergy used/force needed

Science fair project involving the lifting of a weighted dummy at different degrees of knee bending as the starting point. What would be the best way to measure/determine the amount of physical energy used or force needed to lift the dummy? Thanks

Hello Napoleon,
One possibility that comes to mind for your force measurement is a spring balance. This kind of instrument can be used to weigh objects and it can be used to measure a pulling or pushing force on an object. Some examples are shown here:

As you can see from the above link, spring balances have different maximum force capacities. You'll need to select the proper capacity based on the weight of object you'll be lifting.
I hope this helps. Please ask again if you have more questions.
