  2. Bungee Jump - Potential and Kinetic Energy - Physics Forums

    www.physicsforums.com/threads/bungee-jump-potential-and-kinetic-energy.188128

    Yes, there is a limit to the potential energy in a bungee jump. The maximum potential energy can be achieved when the jumper is at the highest point of the jump, right before the cord reaches its maximum length. After this point, the potential energy will decrease as the kinetic energy increases. The jumper will eventually reach a point where ...

    46. 0. You're right, an object can have potential energy and kinetic energy at the same time. Let's say you knock your knife over the table so that you give it an initial kinetic energy as it heads to the ground in addition to its gravitational potential energy that it had from being on the table. In fact, if it were a charged particle in an ...

    Sep 27, 2010. Energy Incline Kinetic Kinetic energy Potential Spring. In summary, a 4.1 kg block slides down a 26.0 deg incline, encountering a spring with a spring constant of 428 N/m. Using relevant equations, the value of d is found to be 0.213 m. To solve for the distance between the point of first contact and the point where the block's ...

    Both potential and kinetic energy are important in a gas tank. Potential energy is necessary to store the fuel and provide the initial energy for the vehicle, while kinetic energy is crucial for keeping the vehicle moving and powering its various functions. 5. How does the potential and kinetic energy in a gas tank compare to other forms of energy?

    Potential & Kinetic Energy of Revolving Object (e.g. Moon) In summary, the moon has a gravitational potential energy given by the formula E = -MmG/r, where M is the mass of Earth, m is the mass of the moon, G is the gravitational constant, and r is the distance between them. This potential energy is negative, indicating that the moon is ...

  7. Catapult spring, Kinetic and Potential energy - Physics Forums

    www.physicsforums.com/threads/catapult-spring-kinetic-and-potential-energy.979422

    A catapult uses potential energy stored in the spring to launch a projectile. When the catapult arm is pulled back, the spring is stretched and potential energy is stored. When the arm is released, the potential energy is converted into kinetic energy, propelling the projectile forward. 3.

  8. Kinetic and Potential Energy on Ramps - Physics Forums

    www.physicsforums.com/threads/kinetic-and-potential-energy-on-ramps.559099

    The formula for kinetic energy is KE = 1/2 * m * v^2, where m is mass and v is velocity. The formula for potential energy is PE = m * g * h, where m is mass, g is acceleration due to gravity, and h is height. On ramps, potential energy can also be calculated using PE = m * g * sin (theta) * x, where theta is the angle of the ramp and x is the ...

    www.physicsforums.com/threads/kinetic-and-potential-energy-problem.754601

    Just use conservation of energy. It's way cleaner and easier. Find the total energy at the bottom of the hill just before the rider enters the rough surface, and use E0 - W = Ef = 0 (because the rider lost all potential energy in coming down the hill which was converted to kinetic energy, and then the rider and sled have -W done on them by the surface)

    Enthelpy, thermal energy, and kinetic vs. potential energy. In summary, the conversation discusses the concept of enthalpy and its relation to energy. Energy is an abstract term that describes the capacity to cause change in a system, while enthalpy is a measure of the amount of energy stored in a system. This is useful in understanding the ...
