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 given to the topic of friction and weight.

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 vector quantity.
Define the SI unit of force, the newton. Describe force as a vector. The study of motion is called kinematics, but kinematics only describes the way objects move—their velocity and their acceleration. Dynamics is the study of how forces affect the motion of objects and systems.
Forces are used to push or pull stationary objects, to stop moving objects, to change direction of moving objects. Forces always exist in pairs: a force of action and a force of reaction (third law of Newton). Action and reaction forces acts on different objects and have equal magnitudes.
23 mar 2023 · The four fundamental forces of nature are gravitational force, electromagnetic force, strong nuclear force, and weak nuclear force. Learn the different types of forces in physics and mechanics, along with examples and diagrams. What is the equation for force. What are the effects of force.
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. Because force has both magnitude and direction, it is a vector quantity.
About 20 different forces are briefly described. The use of free body diagrams is explained. Newton's 1st law of motion is stated and used to define force.
