Forces can be described as a push or pull on an object. They can be due to phenomena such as gravity, magnetism, or anything that might cause a mass to accelerate.

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.

Dec 4, 2025 · 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 …

What is a force? A force is a push or pull on an object. It can make things move, stop, or change direction. For example, types of forces include gravity, friction, and magnetism. Forces are a key part …

A force is a push or a pull. Types of contact forces include the normal and friction forces. Types of non-contact forces include the gravitational, electric, and magnetic forces. When two or more forces act …

Sep 20, 2025 · In physics, forces are broadly categorized into two main types: contact forces and non-contact forces. Contact forces result from direct physical interaction

Mar 30, 2022 · The four fundamental forces of nature are gravity, electromagnetism, the strong interaction, and the weak interaction. Gravity is the attractive force between two masses.

Explore the forces at work when pulling against a cart, and pushing a refrigerator, crate, or person. Create an applied force and see how it makes objects move. Change friction and see how it affects …

Force is push or pull. Unbalanced forces make an object accelerate. Forces on an object are usually balanced: forces in one direction are equal to forces in the opposite direction: No acceleration. …

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. A force is represented …
