... (a) The work required to stretch a spring depends on the square of the amount of stretch. Therefore, to stretch a spring by the amount x requires only 1/4 the work required to stretch it by the amount 2x. In this case, the work required is W0/4. (b) To stretch this spring by 3 cm from equilibrium re ...

... You’ll notice as you pull the spring, that the further you extend the spring, then the greater the force that you have to exert in order to extend it even further. As long as the spring is not streched beyond a certain extension, called elastic limit, the force is directly proportional to the ex ...

... Since both blocks accelerate, there must be a net force acting on each one. The key to solving is to realize that Newton’s second law can be used separately for each block to relate the net force to the acceleration. Note also that both blocks have accelerations of the same magnitude a, since they m ...

5.1 The First Law: The Law of Inertia
... The Atwood’s machine is driven by a net force equal in magnitude to the weight difference between the two mass hangers. You will vary the two masses, m1 and m2, but you will keep the total mass constant. As you move plastic washers from m2 to m1, you will use a photogate to measure the acceleration ...
