Galileo di Vincenzo Bonaiuti de' Galilei was an Italian astronomer, physicist and engineer, sometimes described as a polymath, from Pisa. Galileo has been called the "father of observational astronomy", the "father of modern physics", the "father of the scientific method", and the "father of modern science".

Answer 2

Answer:

The correct option is (c). The work done by a force on a body doesn't rely on the initial velocity of the body.

Explanation:

Work done by any force is that the product of the force within the direction of displacement and therefore the magnitude of displacement.The work done depends on the force and displacement.

$W=\vec{F}\cdot \vec{d}$, when force and displacement is perpendicular to every other workdone is zero. As a result, work done is influenced by the angle between force and displacement likewise because the velocity of the moving object. Hence workdone also depends upon the angle between the force and displacement but not on the rate of the moving object.
