How Fast Was The Box Going When It Hit The Spring? Let the spring be stretched through a small distance d x dx dx. Then work done in stretching the spring through a distance d x dx dx is d W = F d x , dW=Fdx, dW=Fdx, where F is the force applied to
Can Something Have More Than One Type Of Energy? Can something have more than one type of energy? Systems of objects ranging from atoms to planets can be arranged in many ways, resulting in many forms of potential energy: chemical, elastic, electrical (electromagnetic), gravitational, nuclear, and thermal energy. Can energy come in many forms? Energy
Can Something Have Energy Without Moving? Can something have energy without moving? Yes, an object can have energy without having momentum because it can have all potential energy meaning its not moving but it still has energy. Does energy only exist in moving objects? Kinetic and potential energies are found in all objects. If an
How Heavy Is An Energy Capturing Backpack? The whole set up is encased in a frame that the user can wear like a conventional backpack. The energy harvesting backpack weighs around 5 kg (11 lbs). How does a energy capturing knee brace work? When the brace’s generator is engaged, it collects power while slowing down
Do All Things Have Energy? Do all things have energy? And it is quite clearly showing that everything is energy at the most fundamental levels. Is there energy in all things? Essentially, all particles have energy because of both their motion (the kinetic energy is technically part of this) and their mass. But this means
What Factors Influence Potential And Kinetic Energy? What factors influence potential and kinetic energy? The amount of Kinetic Energy that an object possesses is dependent on two factors: mass and velocity. Both of these factors are directly proportional to the kinetic energy. What is the difference between kinetic and potential energy? Potential energy is the
What Factors Determine The Gravitational Potential Energy Stored Between An Object And Earth? What factors determine the gravitational potential energy stored between an object and Earth? Gravitational Potential Energy is determined by three factors: mass, gravity, and height. All three factors are directly proportional to energy. What two factors affect how much gravitational potential energy
What Energy Conversions Occur When A Ball Is Bouncing? What energy conversions occur when a ball is bouncing? Elastic potential energy is what causes a ball to bounce, or rebound, because it is transformed into kinetic energy, which is then used to bring the ball back up. What energy does a bouncing ball have before
Does BART Run On Electricity? Does BART run on electricity? BART is one of the largest consumers of electric power in Northern California, using about 400,000 megawatt hours (MWh) of electricity annually, which is on scale with a small city’s annual consumption. 96% of the energy consumed at BART is in the form of electricity.
Does E Mc2 Apply To Humans? Does E mc2 apply to humans? @AlexP Actually, E=mc2 is applicable (it’s always applicable), but you’re absolutely right that it’s wrong to invoke it in the OP’s context since the m in the equation has noting at all to do with the person’s mass, but with the (really really
