Paper 1 H - SAMPLE SET 1 Q23
23) A student researches potential and kinetic energy. She looks at some data from experiments with motion trolleys and energy.
The trolleys are stationary at the top of the ramp and have a gravitational potential energy of 8 J.
Each trolley has a mass of 1 kg.
Look at the research data on the trolleys.
The trolleys are stationary at the top of the ramp and have a gravitational potential energy of 8 J.
Each trolley has a mass of 1 kg.
Look at the research data on the trolleys.
The student thinks the data is wrong.
Use the data and your understanding of energy transfer to justify why trolley W has the most likely velocity and why X, Y and Z do not. [4]
