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.

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.

Sep 12, 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 …

Mar 23, 2023 · 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.

Types of Force 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 …

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.

Key Points 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...

Force can change the state of motion of an object, making it a fundamental concept in mechanics. It can cause an object to start moving, stop moving, change direction, or change its shape. …

Forces have different magnitudes and directions; this means that some forces are stronger than others and can act in different directions. For example, a cannon exerts a strong force on the …
