A 1.2 kg block is held against a spring of force constant 1.0 x 10^4 N/m, compressing it a distance of 0.15m. How fast is the block moving after it is released and the spring pushes it away?
Work done by a variable force is the measure of the energy transferred when an object is moved by a force that varies in magnitude and direction.
The work done by a variable force can be calculated by multiplying the force applied to an object by the distance it is moved in the direction of the force.
The unit of measurement for work done by a variable force is joules (J).
The main difference between work done by a variable force and work done by a constant force is that the magnitude and direction of the force applied varies in the case of a variable force, while it remains constant in the case of a constant force.
Understanding work done by a variable force is important in various fields of science, such as physics and engineering, as it helps us to analyze the effects of forces on objects and to calculate the amount of energy transferred in a given situation.
