In the case of a bow and arrow when the archer does work on the bow drawing the string back some of the chemical energy of the archers body is transformed into elastic potential energy in To determine the gravitational potential energy of an object a zero height position must first be arbitrarily assigned. Typically the ground is considered to be a position of zero height.
Calculate your homes solar potential. Find out how much solar energy you could harness and how much that could be worthStretch and compress springs to explore the relationships between force spring constant displacement and potential energy Investigate what happens when two springs are connected in series and parallel.
The electric dipole moment for a pair of opposite charges of magnitude q is defined as the magnitude of the charge times the distance between them and the defined direction is toward the positive charge.When objects interact through a force they exchange momentum and kinetic energy. Sometimes the law of conservation of energy is not apparently obeyed.Masses and Springs Basics Masses and Springs Pendulum Lab Projectile Motion Gravity And Orbits Hookes Law Forces and Motion Basics Fluid Pressure and FlowVelocity Speed and Motion Oh My Velocity and speed are very similar ideas but velocity is a vector and speed is not. Suppose we knew that someone was driving at thirty-five kilometers an hour (35 kmhr) but the direction wasnt given.
