Unit test. Level up on all the skills in this unit and collect up to 400 Mastery points! Forceful, forcing, "may the force be with you!"—how do scientists define the term "force", and how do forces make things move? Learn how we can define and measure forces and motion to understand how things ranging from grains of sand to entire planets move.
They describe the true cause behind familiar terms like friction and the normal force. These four basic forces are known as fundamental because they alone are responsible for all observations of forces in nature. The four fundamental forces are gravity, electromagnetism, weak nuclear force, and strong nuclear force.

A force is an action that changes or maintains the motion of a body or object. Simply stated, a force is a push or a pull. Forces can change an object’s speed, its direction, and even its shape. Pushing a door open, pulling it closed, stretching a rubber band—all of these actions require force. Force is a vector quantity—that is, it has ...
Apr 11, 2024 · Force. Force is defined as an external cause that a body experiences as a result of interacting with another body. Whenever two objects interact, a force is exerted on each object. In general-term “To Push or Pull an Object” is defined as the force. The force is the interaction experience by the object because of the other object.
About this unit. Understanding interactions between force, mass, acceleration, and momentum allows us to predict and how an object will move and comes in handy when we're designing things like airplanes or seismically-reinforced buildings. Let's start exploring what these terms mean and how they relate to one another!
1. [noncount] : physical strength, power, or effect. The front of the car took the full force of the collision. instruments used to measure the force of the wind. 2. [noncount] : power or violence used on a person or thing. The police were accused of using excessive force when they made the arrest.
