and final momentum are equal irrespective of their masses and initial velocities. The results show that momentum and kinetic energy of the system is conserved during an elastic collision while only momentum is conserved during inelastic collision. Kinetic energy is not conserved during an inelastic collision. This was found by dividing the final kinetic energy by the initial kinetic and getting a number that was close to one. Which is was fairly close in most cases. Introduction: The purpose of

The conversion of potential energy to kinetic energy is what drives the roller coaster‚ and all of the kinetic energy you need for the ride is there once the coaster goes down the very first hill. Once the coaster gets going‚ there are different types of wheels that help keep the ride smooth. Roller coasters don’t have engines. But they do have energy. Once all passengers are in the coaster‚ the carts get released and begin to roll down the first hill. The force of gravity makes them accelerate downwards

You need to go to bed early so you will have energy in the morning to go to school. Energy gives you the e ability to do work. Energy is everywhere in nature‚ sunlight wind‚ water‚ plants‚ and animals. We use energy everyday. There are two kinds or energy. There’s kinetic energy and potential energy. There are many

and gravity are constant variables while height is a changeable variable. Therefore‚ if the height is increased then so is the potential energy. The maximum kinetic energy is at B. This is because as the cars lose height‚ they speed up (v=d/t). Therefore‚ most of their original potential energy (due to the height) is transformed into kinetic energy (due to the velocity) while some of the energy is turned into heat energy due to friction. Because the rollercoaster has just begun‚ the coaster has not

Kinetic Friction Experiment #13 Joe Solution E01234567 Partner- Jane Answers PHY 221 Lab Instructor- Nathaniel Franklin Wednesday‚ 11 AM-1 PM Lecture Instructor – Dr. Jacobs Abstract The purpose of this experiment was to examine kinetic friction and what factors affect it. We pulled a wood block across a surface to determine whether the surface area of the block or the type of surface affects friction. The surface area did not appear to affect friction‚ since there was a small percent difference

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 *

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
