My problem is with the solution
If we differentiate:
dU/dx = 9x^2 - 7
From where does the negative come from also the j component?
Potential energy is the energy that an object possesses due to its position or condition. It is often described as stored energy, as it has the potential to do work when it is released.
Potential energy and force are related because force is required to change the position or condition of an object, which in turn affects its potential energy. For example, lifting an object to a higher position requires force and increases its potential energy.
The formula for potential energy is PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object.
To differentiate potential energy to find force, we use the formula F = -dPE/dx, where F is the force, PE is the potential energy, and x is the position or variable that is changing. This formula allows us to calculate the force required to move an object to a specific position or height.
One example is a roller coaster, where the potential energy is differentiated to find the force required to move the roller coaster cars up and down the track. Another example is a spring, where the potential energy is differentiated to find the force exerted on an object attached to the spring at different positions.
