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.

Oct 27, 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 …

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 …

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.

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

It is now time to expand our studies to include the quantities that affect motion — mass and force. The mathematical description of motion that includes these quantities is called dynamics. …
