Forces in Motion: Basics

The nature of forces are broadly divided into two categories, and its effects can be presented on an elastic object.

Resultant Forces

A resultant force is the overall effect of two forces or more acting on an object.

Physics: Newton's First Law

Newton's first law is determined by the value of the resultant force on an object, and how that affects its motion.

Physics: Newton's Second Law

Newton's second law describes how acceleration is affected by the mass of an object, or the resultant forces acting on it.

Physics: Newton's Third Law

Newton's third law says that for two objects acting on each other, they exert equal and opposite forces.

Circular Motion

Circular motion of an object occurs when a resultant force acts on the object for it to change direction constantly.

Rotational Effects

Turning forces are useful to take advantage of, as the function of levers and gears.

Forces in Transport

Forces are what allows transport to be able to move, and come to an emergency stop when it needs to.


Momentum is the product of mass and velocity of an object in motion.
