T/F Potential and Kinetic Energy

Question

Indicate which statement is true(T) or false(F). If false then change the word or phrase that is bold and underlined to make it true.

_____ To compare the kinetic energy of two objects moving horizontally, you only need to know the work required to stop each object.

_____ If the speed of a person triples, the person’s kinetic energy triples.

_____ A car with mass m moving with a speed of 4v has the same kinetic energy as a car of mass 16 m moving with a speed of v.

_____ When you use the equation Eg = mgh, the only condition on h is that is must be measured in a straight line.

_____ A 10-kg and 5-kg mass held above the Earth at a height of 10 m will have the same gravitational potential energy.

_____ When energy changes from one form to another absolutely no energy is lost.
