Study Notes

Understanding Force

A force is an influence that alters an object's motion.
Forces can instigate a change in velocity in objects with mass, enabling acceleration from rest.
Conceptually, a force can be viewed as either a push or a pull acting on an object.
Force is characterized by two key properties: magnitude (how strong the force is) and direction (which way the force acts), categorizing it as a vector quantity.
The standard unit for measuring force in the International System of Units (SI) is the newton (N).
The symbol used to represent force in equations and calculations is "F".
