Question

Give two examples where using conservation of energy to solve a problem is easier than the methods you learned earlier in the course

Answer 1

The examples where using conservation of energy to solve a problem is easier than other methods are:

1. Pendulum

2. Nuclear Power Plant

The principle of the conservation of energy says that:

Energy within an isolated system is neither created nor destroyed, it simply changes from one type of energy to another.

1. Pendulum:

As the pendulum swings down:

gravitational potential energy of the pendulum →kinetic energy of the pendulum.

As the pendulum swings up: kinetic energy of the pendulum→ gravitational potential energy of the pendulum.

2. Nuclear Power Plant:

Nuclear energy (from the decay of uranium) → thermal energy of water

→kinetic energy of a turbine →electrical energy + thermal energy (from friction in the turbine and transmission lines)
