Gravitational potential energy

Abstract The aim of this experiment was to establish whether speed affects braking distance of a car travelling down a ramp at different heights. The method involved performing a controlled test before changing the angle of the ramp for the other four tests. To do this, three text books were used to prop up the ramp and the height was increased for each test. These trials were done five times, changing the variable after each set, measuring the speed and changing the angle of the ramp. The results

Alternative Energy Introduction: Last year for my science fair project I personally invented my own version of a sun tracking solar panel. The solar panel was able to produce three watts of power per hour regardless of its small three-inch by three-inch size, showing me that having direct access to the sun can increase the amount of watts gained multifold. This year, instead of researching over the topic of solar panels, I instead inquired alternative methods of producing energy from economical

about different types of physics. Roller coasters are a commonly used example of potential and kinetic energy, and also by learning about roller coasters a person can learn about forces. Roller coasters can be very different, but they usually follow the same basic track to make the ride more thrilling.The ride starts when the chain pulls the cars up the first hill. The first hill is the tallest, so the potential energy is at its most at the

amount of kinetic energy a ball possess after collision. The ball that is travelling down the ramp with a slightly higher angle, will possess more kinetic energy before collision but after collision it will posses less kinetic energy because of it being an elastic collision where energy is conserved and transfers some energy to the ball travelling down the less steep ramp with less momentum. Therefore the ball travelling down the ramp that is not as steep will possess more kinetic energy after collision

ball bounce height was 110.6 cm. My hypothesis was supported. WHY DID IT HAPPEN? When the ball was held at a higher height, it had more Gravitational Potential Energy, because G.P.E depends on height above the ground, and mass of the object (mass remained the same). Since the ball had a greater amount of G.P.E, it converted into more kinetic energy, or motion energy, when it was dropped. So, it hit the ground with a

the siphon effect works with the combination of water and gravity at their finest. H2O has its own variety of different potential energies. Gravitational potential energy is at work all night, all day, and every second in-between, while water has its own potential energy due to having either low or high-pressure. Water's total potential energy includes gravitational potential

This report is on energy. Energy is the strength and vitality required for sustained physical or mental activity. What that was saying is that for everything you want to do, you have to have the physical ability and the mind set to do it. Energy and work are the two most important things in human society. Work is activity involving mental or physical effort done in order to achieve a purpose or result. That means, is you want something done, DO IT. Kinetic energy is energy that a body possesses by

the steepness of the ramp decreases, the car’s velocity decreases. The car’s velocity changes as it goes down a ramp because of work and energy, as the change of a car’s potential energy is its mass times the change in its height times the current gravitational acceleration. This loss of gravitational potential energy increases the kinetic energy. The kinetic energy

Pankaj Kandel M. Decovsky Physics 9 December 2015 Essay - Energy in theme parks Dear Management Team, I have recently received a letter from the management team that says the management wants to cut the budget of the engineering team, stating that engineering team can hire non-engineers to design and maintain our rides. This would be a foolish step to take because physics is the key behind the success of all rides, each and every ride follows the same physics concept to design secure operation
