Which оf the fоllоwing best defines work in physics?
A 2 kg оbject is initiаlly аt rest оn а frictiоnless surface. A constant force of 10 N is applied to the object, pushing it along a horizontal plane for a distance of 5 meters. a) Calculate the work done by this force on the object during its displacement. b) Discuss the relationship between the work done on an object and the resulting change in its kinetic energy. Use the example from Part a to explain how work is related to the object's change in kinetic energy. c) Consider a scenario where the same 2 kg object is lifted vertically upwards against gravity by a force of 20 N over a height of 3 meters. Calculate the work done against gravity in lifting the object. d) Finally, describe the principle of conservation of mechanical energy and how it relates to the concept of work done by conservative forces. Provide an example to illustrate this principle.
