Forces in physics can be contact forces or field forces, acting either through direct physical contact or at a distance. Examples of forces include push, pull, tension, gravity, and friction.
In physics, a force is any influence that causes an object to undergo a change in movement, direction, or construction. Forces do not have to be between objects that are touching. They can act at a distance through field forces, such as gravitational forces.
There are different types of forces, including contact forces like push, pull, and tension, and field forces like gravitational force. For example, when you push a book across a table, you are applying a contact force.
Gravity, tension, and friction are examples of forces that we encounter in our daily lives. These forces can be categorized based on their origin, how they are transmitted, or their effects.
