RP 3P1 Force and Motion - NC Science Wiki
... Since everything is moving, there is no fixed reference point against which the motion of things can be described. All motion is relative to whatever point or object we choose. Thus, a parked bus has no motion with reference to the earth's surface; but since the earth spins on its axis, the bus is m ...

Nature of the Induced E
... (a) The e.m.f. induced in the coil is an alternating one, since it is alternately positive and negative in direction. (b) The e.m.f. undergoes one complete "cycle" of changes in the time taken by the coil to make one complete revolution. This is shown by the fact that the graph begins to repeat itse ...

... A proton moves with a speed of 1.0x105 m/s through the Earth’s magnetic field, which has a value of 55µT at a particular location. When the proton moves eastward, the magnetic force is a maximum, and when it moves northward, no magnetic force acts upon it. What is the magnitude and direction of the ...

Vector Mechanics for Engineers: Dynamics
... • When a particle of mass m is acted upon by a force F , the acceleration of the particle must satisfy r r F = ma • Acceleration must be evaluated with respect to a Newtonian frame of reference, i.e., one that is not accelerating or rotating. • If force acting on particle is zero, particle will not ...
