Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.

Question

When the force acts in the opposite direction of motion, then the speed will increase or decrease?

Expert Solution

Step 1

The force acting on a body of mass 'm' and acceleration 'a' is given by,

$F = m a$
