A "push" refers to a force that moves an object away from a person or another object. In physics, pushes are considered contact forces, meaning they require direct interaction between the objects involved. For example, when you push a shopping cart, you apply force to move it forward. In everyday life, pushes can be seen in various activities, such as pushing a door to open it or pushing a swing to make it move. Understanding pushes helps us grasp basic principles of motion and force, which are fundamental concepts in physics.
