Types of Forces - The Physics Classroom
A force is a push or pull that acts upon an object as a result of that objects interactions with its surroundings. In this Lesson, The Physics Classroom differentiates between the various types of forces that an object could encounter. Some extra attention is …
Force - Wikipedia
A force is an influence that can cause an object to change its velocity unless counterbalanced by other forces. The concept of force makes the everyday notion of pushing or pulling mathematically precise. Because the magnitude and direction of a force are both important, force is a …
What is Force? - Definition, Unit, Types, Formula, Applications
Force is a physical cause that can change an object’s state of motion or dimensions. There are two types of forces based on their applications: Contact Force; Non-Contact Force

What is a force? - BBC Bitesize
Forces are pushes or pulls. They are measured in newtons. Forces are just pushes and pulls in a particular direction. Forces are shown by arrows in diagrams. The direction of the arrow shows...
Force | Definition & Formula | Britannica
2024年12月18日 · force, in mechanics, any action that tends to maintain or alter the motion of a body or to distort it. The concept of force is commonly explained in terms of Isaac Newton ’s three laws of motion set forth in his Principia Mathematica (1687).
Force Definition in Science
2022年3月30日 · In physics and other sciences, a force is a push or pull on a mass that can change the object’s motion. Force is a vector quantity, meaning it has both magnitude and direction. The symbol for force is the capitol letter F. A famous example of an equation for force is Newton’s second law: F = m*a. Here F is force, m is mass, and a is acceleration.
The Meaning of Force - The Physics Classroom
Force is a quantity that is measured using the standard metric unit known as the Newton. A Newton is abbreviated by an "N." To say "10.0 N" means 10.0 Newton of force. One Newton is the amount of force required to give a 1-kg mass an acceleration of 1 m/s/s. Thus, the following unit equivalency can be stated: A force is a vector quantity.
5.2: Forces - Physics LibreTexts
In most situations, forces are grouped into two categories: contact forces and field forces. As you might guess, contact forces are due to direct physical contact between objects.
Definition of Force in Physics - ThoughtCo
2019年7月3日 · Force is a quantitative description of an interaction that causes a change in an object's motion. An object may speed up, slow down, or change direction in response to a force. Put another way, force is any action that tends to maintain or alter the motion of a body or to distort it. Objects are pushed or pulled by forces acting on them.
