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 that acts on an object due to the interaction with another object. Force is measured in newtons (N). Forces are divided into contact forces and non-contact forces. A ...

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

May 27, 2025 · Forces are the invisible agents that change the motion of objects, that make things speed up, slow down, or change direction. They are the unseen hands that govern everything from a …

Jun 27, 2024 · Newton’s Laws of Motion Sir Isaac Newton’s laws of motion explain the relationship between a physical object and the forces acting upon it. Understanding this information provides us …

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.

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. …
