Curved Motion
According to Newtons first law, if the net force
on an object is zero, then the object will remain
at rest or will move in a straight line with a
constant speed. For an object to move along a
curve, there must be a net force on the
object. One specific case that we will study is
motion in a circle with a constant speed, i.e.
uniform circular motion.
