15. Stored energy or energy due to position is known as gravitational potential energy . Gravitational potential energy is the energy due to the position of an object in a gravitational field.

16. The formula for calculating potential energy is

U=mgh

where m is the mass of the object, g is the gravitational acceleration and h the heigth of the object above the ground.

17. The three factors that determine the amount of potential energy in an object are :

- the mass

- the acceleration of gravity, g

- the height of the object relative to the ground

18. Potential energy is measured in units of Joules. Potential energy is a form of energy, so it is measured in Joules (J), which is the SI unit of the energy.

19 Mass must be measured in units of kilograms (kg). Mass is a scalar quantiy expressing the amount of matter in an object; the SI unit of the mass is the kilogram, kg.

20. Gravitational pull must be measured in units of Newton (N). Gravitational pull is a force, therefore it is measured in Newtons.

21. The value of the g constant (the acceleration of all objects due to gravity) on earth is 9.8 m/s^2 . The acceleration of gravity is the acceleration due to the force of gravity, pulling all objects towards the Earth's centre. Its value is slightly different at different locations on Earth.

22. Height must be measured in units of metres (m). Height is a length, and the SI unit of the length is the metre.

23. Kinetic energy is the energy matter has as a result of its mass

and speed. In fact, the kinetic energy of an object is given by

$K=\frac{1}{2}mv^2$

where m is the mass of the object and v its speed.

24. The more mass an object has the more Kinetic energy it has. As we can see from the previous formula, kinetic energy is proportional to the mass, so the more mass an object has, the more kinetic energy it has.

25. The more speed an object has the more Kinetic energy it has. As we can see from the previous formula, kinetic energy is proportional to the square of the speed, so the more speed an object has, the more kinetic energy it has.

26. The SI (metric) unit for energy is Joule and the symbol is J.

The particle in a two-dimensional well is a useful model for the motion of electrons around the indole ring (3), the conjugated cycle found in the side chain of tryptophan. we may regard indole as a rectangle with sides of length 280 pm and 450 pm, with 10 electrons in the conjugated p system. as in case study 9.1, we assume that in the ground state of the molecule each quantized level is occupied by two electrons. (a) calculate the energy of an electron in the highest occupied level. (b) calculate the frequency of radiation that can induce a transition between the highest occupied and lowest unoccupied levels. 9.27 electrons around the porphine ring (4), the conjugated macrocycle that forms the structural basis of the heme group and the chlorophylls. we may treat the group as a circular ring of radius 440 pm, with 20 electrons in the conjugated system moving along the perimeter of the ring. as in exercise 9.26, assume that in the ground state of the molecule quantized each level is occupied by two electrons. (a) calculate the energy and angular momentum of an electron in the highest occupied level. (b) calculate the frequency of radiation that can induce a transition between the highest occupied and lowest unoccupied levels.
