5 Questions
In physics, what is force and how is it represented mathematically?
Force is an influence that can cause an object to change its velocity. It is represented mathematically as a vector quantity, often denoted by the symbol $F$.
What is the SI unit of force and what symbol is used to represent force?
The SI unit of force is the newton (N), and force is often represented by the symbol $F$.
How does force play a central role in classical mechanics?
Force plays a central role in classical mechanics by figuring in all three of Newton's laws of motion, which specify that the force on an object with an unchanging mass is equal to the product of the object's mass and the acceleration that it undergoes.
What are the types of forces often encountered in classical mechanics?
Types of forces often encountered in classical mechanics include elastic, frictional, contact or 'normal' forces, and gravitational.
What is the rotational version of force and what changes does it produce in an object?
The rotational version of force is torque, which produces changes in the rotational speed of an object.
