Force and Motion-wk3

Physics The branch of Science dealing with matter and energy.  Scientists who work in physics are called physicists.  They study such things as moving objects
potential energy stored energy
kinetic energy the energy of a moving object.
conservation in physics, the idea that something cannot be destroyed.  For example, energy is always conserved, but may change from one form to another.
center of gravity the point in an object where the object’s weight seems to be centered. 
effort The amount of force needed to move and object from one place to another
G-force the force that acceleration puts on a coaster rider
centrifugal force movement or tending to move away from a center.
positive g force makes you feel heavier
negative g makes you feel like you are going to fly off the ride
