The formula for calculating the force done by a spring is F = -kx, where F is the force, k is the spring constant, and x is the displacement from the equilibrium position.
The weight of an object does not directly affect the force done by the spring. However, the weight does determine the displacement of the spring and therefore affects the magnitude of the force.
The direction of the force done by the spring is always opposite to the direction of the displacement from the equilibrium position. This means that if the object is pulled down, the force done by the spring will be directed upwards.
The spring constant directly affects the magnitude of the force done by the spring. A higher spring constant means a stiffer spring, resulting in a greater force for a given displacement.
Yes, the force done by the spring can be negative. This occurs when the object is pulled in the opposite direction of the spring's equilibrium position. Negative force indicates that the spring is compressing rather than stretching.
