A simple force is a type of force that acts on an object without changing its shape or size. It can be either a push or a pull and has both magnitude and direction.
Some examples of simple forces include gravity, friction, tension, and normal force. For instance, gravity is a downward force that pulls objects towards the center of the Earth, while friction is a force that opposes motion when two surfaces are in contact.
A simple force is a single force acting on an object, while a net force is the combination of all forces acting on an object. Simple forces can cancel each other out, resulting in a net force of zero, but they can also add up to create a net force with a different magnitude and direction.
The unit of measurement for simple force is Newton (N). This unit is named after Sir Isaac Newton and is defined as the force needed to accelerate a 1 kilogram mass at a rate of 1 meter per second squared.
The magnitude of a simple force can be calculated using the formula F = m x a, where F is force, m is mass, and a is acceleration. If the object is not accelerating, the formula can be simplified to F = m x g, where g is the acceleration due to gravity (9.8 m/s^2 on Earth).
