Abstract Two activities were performed in this experiment. For the first activity, the weights of the different members of the group were each computed and were used in order to determine how much work and power each member exerted in climbing up and down the stairs while being timed. From the data obtained, it is apparent that as one is faster, more power and work is exerted. For the determination of energy of a tossed ball, the data obtained shows that potential energy is inversely proportional to kinetic energy.

The conservation of mechanical energy can be determined by multiplying the force exerted by a person to the displacement. This was demonstrated by going up and down the stairs. As for the relationship of kinetic energy to potential energy, as an object is thrown upwards the kinetic energy decreases while the potential energy increases. And lastly, the power output of a person going up the stairs id greater than when the person is going downstairs due to the amount of force needed to go against the pull of gravity as the height increases.
