that as the drop height of the golf ball increases‚ the crater size and the kinetic energy also increase. This is more clearly illustrated in figure 1 and 2. Figure 1 shows that as the velocity increases‚ the crater size also increases. Like wise‚ figure 2 shows that as the kinetic energy increases the crater size also increase. The trendiness in both figure 1 and 2 suggest that there is a point where more speed/kinetic energy will not increase the crater size. Discussion Figure 1 shows that there

Application of Energy ------------------------------------------------- Forms of energy Main article: Forms of energy Energy exists in many forms: Heat‚ a form of energy‚ is partly potential energy and partly kinetic energy. In the context of physical sciences‚ several forms of energy have been defined. These include: * Thermal energy‚ thermal energy in transit is called heat * Chemical energy * Electric energy * Radiant energy‚ the energy of electromagnetic radiation *

At present‚ there are about 1600 known isotopes‚ of which only one-sixth are stable. The unstable isotopes lose energy by emitting ionising particles or radiation through the process of radioactive decay. Ernest Rutherford and later Paul Villard discovered the three

force of the rubber band is causing in to travel forward. Kinetic energy is used to pull back the catapult‚ and get the rubber band ready for launch. The rubber band contains elastic potential energy. That elastic potential energy converts to kinetic energy‚ and the marshmallow launched gains gravitational potential energy while losing kinetic energy‚ until it reaches its maximum height. At its maximum height it has the least amount of kinetic energy‚ but the greatest potential energy. As it falls in

Experiment 5: Friction Laboratory Report Charles Sanchez‚ Geminesse Sianghio‚ Ferguie Solis Department of Chemistry College of Science‚ University of Santo Tomas España Street‚ Manila Philippines Abstract In this experiment‚ a block of wood is used to observe friction on different surfaces such that an extra weight is also added to the block of wood to measure the same units under the different surfaces. With also the use of lubircant a member of the group was asked to observe the

On the second activity‚ the graphs of the potential energy vs. time‚ kinetic energy vs. time‚ and mechanical energy vs. time of a ball thrown vertically were all predicted. Finally‚ the ball was tossed on the motion detector and the graphs of potential‚ kinetic‚ and mechanical energies vs. time were all produced using the Logger Pro. Introduction Work is said to be an act of exerting force. Whatever it is that can
