The picture to the left shows a train as it approaches a hill,

The train can only make it over the hill if it approaches at its top speed because it will lose speed as it climbs. What changes are taking place in the trains potential and kinetic energy as it climbs the hill?

• The train's potential energy is increasing and its kinetic energy is increasing.

• The train's potential energy is decreasing and its kinetic energy is decreasing.

• The train's potential energy is decreasing and its kinetic energy is increasing.

• The train's potential energy is increasing and its kinetic energy is decreasing.
