What is energy? differentiate between potential and kinetic energy?

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

Where is the potential energy throughout the loading, cocking, and releasing of the trebuchet?
