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.

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 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.

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...

Dynamics is the study of the forces that cause objects and systems to move. To understand this, we need a working definition of force. An intuitive definition of force —that is, a push or a …

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 …

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 …
