Question

What energy/work is done by those people riding a running rollercoaster car?

Will the work/energy be any different if the rollercoaster car is empty but still running?

It what way will it be different?

Explain scientifically...

Thank you and God bless!

Answer 1

Mass, and therefore weight will change, which will affect the kinetic energy which is defined as 1/2*m*v^2

If mass is increased, then kinetic energy will have to increase as well.
