Forces play a crucial role in understanding how objects move and interact with each other in the physical world. Simply put, a force is a push or pull that can cause an object to accelerate, decelerate, or change its direction.

There are several types of forces that we encounter in our daily lives. One common type is the force of gravity. When you drop an object, it falls to the ground due to the gravitational force. Another common type of force is friction, which opposes the motion of objects sliding against each other. For example, when you slide a book on a table, friction slows it down.

Additionally, there are forces that humans apply consciously, such as pushing a shopping cart or kicking a soccer ball. These forces can cause objects to move or change their state of motion.
