Particle accelerators are often framed as exotic machines built only to chase obscure particles, but they are really precision tools that use electric fields and magnets to steer tiny beams of matter ...

Draw a single free body diagram (FBD) of the bar and the particle. Step 2: Kinetics (Work/energy) Looking at your FBD above, which forces, if any, do work that is not a part of the potential energy of ...

Looking at your FBD above, which forces, if any, do work that is not a part of the potential energy of the system? If there are none, then energy is conserved. Write down the individual contributions ...
