Concept explainers

Simple harmonic motion
Simple harmonic motion is a type of periodic motion in which an object undergoes oscillatory motion. The restoring force exerted by the object exhibiting SHM is proportional to the displacement from the equilibrium position. The force is directed towards…
Simple Pendulum
A simple pendulum comprises a heavy mass (called bob) attached to one end of the weightless and flexible string.
Oscillation
In Physics, oscillation means a repetitive motion that happens in a variation with respect to time. There is usually a central value, where the object would be at rest. Additionally, there are two or more positions between which the repetitive motion tak…

Question

A heavy box is to be moved from the floor to a sturdy shelf 2 meters above the floor. You have two possible methods to move the box: 1) lifting the box straight up the 2 m ; or 2) sliding the box up a long, frictionless ramp to the shelf. Which method requires more mechanical work?
