When a trebuchet counterweight is hoisted by soldiers, what form of energy is transferred into the machine as work? 2. what is the relationship between the mass of the counterweight and the amount of work done on the projectile? 3. describe how lifting a counterweight is doing work using the formulaw = fd. 4. what force must be overcome to lift the counterweight? 5. if the mass of the counterweight increases by adding more mass, how does the force required to lift the counterweight change? 6. how is the work done to hoist the counterweight related to the potential energy of the counterweight at its specified height? 7. if energy is conserved, describe the kinetic energy of the projectile in relation to the work in and the potential energy of the counterweight. 8. provide a well-written hypothesis that can explore the function of the counterweight in a trebuchet. 9. identify the dependent and independent variables in your experiment. 10.where is a safe place to use your trebuchet? 11.how will you determine the work done to the counterweight to hoist it to the catapulting lever? 12.how will you measure the distance the projectile flies? 13.how will you use the dependent variable and independent variable in your data table? 14.what factors need to be kept consistent during the experiment? 15.why is it important to do multiple trials for each different counterweight and then calculate the average?
