... because, as the proof on the last slide shows, there would be another force (friction) in addition to the contact forces. Friction wouldn’t cancel out, and it would be a net force on the system. The only way to conserve momentum with an external force like friction is to make it internal by includin ...

... According to Fleming’s left hand rule, this force acts at right angles to CD, towards AB in the plane of the paper. Similarly, an equal and opposite force is exerted on the wire AB by the field of wire CD. Thus when the currents in the two wires are in the same direction, the forces between them are ...

... What this says is that if we know the voltage at every point within a volume of interest and if A is unchanging, then we can derive the electric field. To derive the voltage at any point within a volume of interest, it turns out that we only need to know where the electric charges are. This is illus ...

... Keep it going: It usually requires very little force to keep a trailer going—just enough to overcome the friction between the wheels and the axles. (You can coast on a bicycle for a long way.) Newton’s first law says that an object will continue to move in a straight line at constant speed unless it ...

... The platter of the hard drive of a computer rotates at 7200 rpm (rpm = revolutions per minute = rev/min). (a) What is the angular velocity (rad/s) of the platter? (b) If the reading head of the drive is located 3.00 cm from the rotation axis, what is the linear speed of the point on the platter just ...

... that the electric field does work on a charged particle (it produces acceleration or deceleration) while the magnetic field does not do any work on the moving charge. This is a direct consequence of the Lorentz force law: dWmagnetic = Fmagnetic ∑ dl = q[( v ¥ B ) ∑ v ]dt = 0 We conclude that the mag ...
