Question

The given graph shows potential energy and kinetic energy plotted against time of a ball thrown straight up from the 10 storey building.
At what point on the graph does the kinetic energy of the object decrease while the potential energy increases?

• A. True
• B. False

Answer 1

The correct option is B False

When ball is thrown straight up from a $10$ storey building, its height increases and velocity decreases i.e.potential energy increases and kinetic energy decreases.It means that graph line of potential energy should go up and of kinetic energy down , this is shown in graph by point $A$.
