... Q19) A block is attached to the end of an ideal spring and moved from coordinate xi to coordinate xf . The relaxed position is at x = 0. The work done by spring is positive if: 1) xi = 2cm and xf = 4cm 2) xi = -2 cm and xf = 4cm 3) xi = -2 cm and xf = -4 cm 4) xi = 2 cm and xf = -4 cm 5) xi = -4 cm ...

Note that as well as any unbalanced forces acting on each object the acceleration of each object will dep ...

Newton`s Three Laws of Motion
... • A force is what we call a push or a pull, or any action that has the ability to change motion of an object. • The metric unit used to describe force is called the Newton (N). One Newton is equal to: 1 Kg x 1 m/s/s Thus, one Newton of force causes a one kilogram object to accelerate at a rate of on ...
