Questions  High School Physics Questions  Problem # 1  Do
heavier objects fall more slowly than lighter objects?  See
solution  Problem # 2  Why do objects float in liquids denser
than themselves?  See solution  Problem # 3  A particle is
moving around in a circle and its position is given in polar
coordinates as x = Rcosθ, and y = Rsinθ, where R is the radius
of the circle, and θ is in radians. From these equations derive
the equation for centripetal acceleration.  See solution
Problem # 4  How come in free fall you feel weightless even
though gravity is pulling down on you? (ignore air resistance
when answering this question).  See solution  Problem # 5  What
is the difference between centripetal acceleration and
centrifugal force?  See solution  Problem # 6  What is the
difference between energy and power?  See solution  Pro
