Chapter 5 – Force and Motion I

Chapter 5 – Force and Motion I I. Newton’s first law: If no net force acts on a body, then the body’s velocity cannot change; the body cannot accelerate v = constant in magnitude and direction. - Principle of superposition: when two or more forces act on a body, the net force can be obtained by adding the individual forces vectorially.

Then, the fact that an electric field changing with time gives rise to a magnetic field, is the symmetrical counterpart, and is FIGURE 8.2 (a) The electric and magnetic

consequence of the Faraday’s law of induction, a changing magnetic field can produce an electric field, according to S d d dt ∫Es⋅ =− ∫∫B⋅dA GG GG v (13.1.2) One might then wonder whether or not the converse could be true, namely, a changing electric field produces a magnetic field. If so, then the right-hand side of Eq. (13.1.1) will
