Here is a spring mounted vertically. Also, there is a hanger for some masses on the end. Now suppose I measure the location of the bottom of the mass holder. Then I place a 250 gram mass in the holder ...

The mass is just sitting there motionless. There is no acceleration and it is in equilibrium. What does this mean? This means that the net force in the y-direction (vertical direction) must be zero. I ...

Why is pancake syrup an example of a resistive force? Some forces are called contact forces because they require objects to touch. One is tension force, found in stretched wires. Another is the force ...

The questions in this quiz are suitable for GCSE physics students studying change of shape, Hooke's law, energy stored in a spring and how forces affect the extension of a spring. If you struggled ...

To investigate experimentally the extension of a spring and how it is related to the applied force, and recall that the extension of a spring is directly proportional to the force applied, provided ...
