Kinetic Energy and Work
... We can use the equation above to define the SI unit for work (the joule, symbol: J ). An object of mass m = 1kg that moves with speed v = 1 m/s has a kinetic energy K = 1J Work: (symbol W) If a force F is applied to an object of mass m it can accelerate it and increase its speed v and kinetic energy ...

... When the spring is fully compressed, it exerts a force F on the block, and when the spring is fully extended, the force it exerts on the block is -F. What is the force of the spring on the block at (a) equilibrium (neither compressed nor stretched), (b) halfway between maximum stretch and equilibriu ...
