10 Questions
What is the direction of the spring force when an object is displaced from its equilibrium position?
Towards the equilibrium position
What is the effect of a large spring constant on the force produced by the spring?
It produces a large force for a small displacement
What is the unit of the spring constant k?
N/m
What is the relationship between the force applied to the spring and the displacement of the spring?
F app is directly proportional to x
What happens to the displacement of an oscillating object during one full cycle?
It continually changes, first decreasing and then increasing
What is the effect of gravity on the oscillation of a spring?
It has no effect on the oscillation
How can the spring constant k be measured?
By applying a force and measuring the displacement
What is the characteristic of a spring with a small spring constant?
It is loose and doesn't pull back with much force
What is the direction of the force exerted by the spring on an object?
Towards the equilibrium position
What is the significance of the equilibrium position in the oscillation of a spring?
It is the position of zero displacement
