... been constant, and since F = ma, the acceleration was also constant, so the constant acceleration formulas could be used. However, if the forces are dependent upon time, t, velocity, v, or displacement, x, then the constant acceleration formulas cannot be used. In situations where the forces are not ...

... charges attract each other. However, we were also told that the balls could also have no charge (i.e. neutral charge). If an object with a neutral charge is brought close to a charged object, they will always attract each other. This is due to induction – the charged object will induce the electrons ...

... The motion of a particle is governed by Newton’s three laws of motion. First Law: A particle originally at rest, or moving in a straight line at constant velocity, will remain in this state if the resultant force acting on the particle is zero. Second Law: If the resultant force on the particle ...
