Potential energy

Work and Energy Worksheet Section 1 Work: 1. A person pulls a toboggan for a distance of 35.0m along the snow. The force in the rope (tension) is 94.0N. How much work is done on the sled? Solution: W= Fd W= 94.0N x 35.0m W= 3290 Nm or J 2. The cable of a large crane applies a force of 2.2x10^4N to a demolition ball as it lifts it vertically a distance of 7.6m. a) How much work is done on the ball? b) Is the work positive or negative? Why? Solution:

objects, we often talk about energy. There are different kinds of energy. One kind is called kinetic energy. Anything that is moving has kinetic energy, and the faster it is moving, the more kinetic energy it has. Another kind of energy is potential energy. We measure potential energy of an object as its height above the ground. Why do we say a ball being held up has potential energy? If the ball was dropped, gravity would

Longmont, solar energy may be the best option, although Hydro power, Biomass, and Geothermal all present options. For Utica, solar energy potential was very low, while the potential for Hydro power is high and most likely that best option. For Cedar Rapids, solar energy potential was also relatively low, while Biomass presents the greatest potential. Yuma has extremely high potential for solar energy, so this seems to be the best option, but also has high potential for Geothermal energy and Hydro power

the potential energy into kinetic energy as the car excels down the hill at high speeds. After this the kinetic and potential energy rock back and forth throughout the thrilling ride. At the beginning of a roller coaster a winch pulls the car to the top of the ride. This energy does not disappear but is instead saved up by the car the higher it goes and uses this, what we call potential energy, to parachute down the summit. As it does so it is turning that potential energy into kinetic energy that

WORK and ENERGY Work done by a constant force 1- The drawing shows a plane diving toward the ground and then climbing back upward. During each of these motions, the lift force acts perpendicular to the displacement , which has the same magnitude, 1.7 × 103 m, in each case. The engines of the plane exert a thrust , which points in the direction of the displacement and has the same magnitude during the dive and the climb. The weight of the plane has a magnitude of 5.9 × 104 N. In both motions

Potential energy and kinetic energy: PE= mass x gravity x height KE= 1/2 MV2 The soccer ball has potential energy when it’s in the air, when you kick the ball it turns into Kinetic energy when it is moving. If the soccer ball is on the ground there is no potential energy because it’s related with height, when you kick the ball the kinetic energy from the player passes through the ball. Momentum: Momentum = mass • velocity Momentum is velocity of object times it’s mass. When we are striking

of potential energy to kinetic energy using a model roller coaster track? II. Background Research Did you ever wonder how a roller coaster works? Why does one roller coaster go faster than another at certain points on the ride? This paper will discuss how potential energy turns into kinetic energy at different points along the track of a roller coaster. The important terms that will be discussed are potential energy (stored energy), kinetic energy (energy of motion), gravitational potential energy

their knees, which stores elastic potential energy in their legs. This elastic potential energy is also referred to as strain energy. As the legs are bent the muscles and tendons are stretched in a way that stores this strain energy(biochmechanics). The greater the bend and stretching in the legs, the greater the power generated as the legs are extended(biomechanics). As the tennis player extends their legs this elastic potential energy is converted to kinetic energy and a ground reaction force is

have energy because of their position, or where they are. When you hold a rubber ball above your head, it has potential energy, or saved energy. When you drop the ball, it falls to the ground because of gravity, and then it bounces back up. The potential energy in the ball turns into kinetic energy, or the energy of movement, when the ball falls and bounces. Potential energy is stored, or saved, energy. Your bike at the top of a big hill and a spring that’s stretched both have potential energy. When

roller coaster “The Explosion” shows the First Law of Thermodynamics, the first law states that energy will be conserved. Our roller coaster conserves energy by reaching its highest peak and flowing with the energy that it has built up. It shows many different types of energy. An example of that would be Kinetic and Potential energy. Kinetic energy is the energy of movement and Potential energy is energy stored in an object. Work and power however are not involved in the motion of our rollercoaster
