Energy - Spring
... (PEgravitational = mgy), but we do not have to include the gravitational potential energy term if we measure the spring length from the hanging equilibrium position. We can then concentrate on the exchange of energy between kinetic energy and elastic potential energy. If there are no other forces ex ...

electric potential
... two or more charged particles, we can assign an ELECTRIC POTENTIAL ENERGY U to the system. The change in potential energy of a charge is the amount of work that is done by an external force in moving the charge from its initial position to its new position. It is the negative of the work done by the ...

Homework #8: Magnetic Force and Biot-Savart Law
... a. [3 points] What current I in the loop would exactly balance the weight of the mass? b. [7 points] Suppose we now increase the current such that the magnetic force exceeds the weight of the mass. This causes the loop to rise and thus, lifts the mass. What is the work done to lift the wire? What fo ...

Elastic Collisions
... Suppose we have a many-body system. In such systems, the concept of momentum becomes particularly useful. Let’s see why. In general, two kinds of forces can act on the bodies in the system. There are internal forces between the bodies, and external forces acting on individual bodies. In what follows ...
