Forces

• We require forces to set things in motion. A force can either push or pull objects. By altering the magnitude of the force, we can make objects move faster, slower, or come to a halt. Additionally, various surfaces can influence how forces act upon moving objects.
• Forces are essential for initiating movement in objects. They can manifest as pushes or pulls, influencing an object's speed or bringing it to a stop. The nature of different surfaces can also modify how forces impact moving objects.
• Forces can be categorized into two primary types: push and pull. A push force moves objects away from the source of force, while a pull force draws objects closer to the source.
• Consider a scenario where you push a book on a table. The force applied causes the book to move across the table surface until the force is removed or countered by an opposing force.
• In contrast, imagine a situation where you pull a toy car with a string. The pull force exerted on the car causes it to move towards you until the force is released or balanced by an opposing force.
