What is force
Force is defined as a push or pull that causes an object to accelerate, or change its speed and/or direction. It is an interaction between two objects and can be either attractive, pushing objects together, or repulsive, pushing objects apart. A common example of a force is gravity, which is the force that pulls an object toward the center of the Earth. This force is constant and affects all objects on Earth. Another example is friction, which is the force that acts between two surfaces when they are sliding against each other. Force can be measured in units of Newtons (N). One Newton is equal to the force required to accelerate one kilogram of mass at the rate of one meter per second squared. An analogy to help understand force is to think of a rubber band. When the rubber band is stretched, the force of the rubber band is pulling the object in an opposite direction. A fun fact about force is that it is the reason behind why a feather and a bowling ball dropped from the same height will hit the ground at the same time. This is because the force of gravity is the same for both objects, even though the feather is much lighter than the bowling ball.
