Newton's second law states that the acceleration of an object depends on the net force acting on it and its mass. This relationship is expressed by the formula F = ma , where F is the net force, m is the mass, and a is the acceleration. Essentially, the greater the force applied to an object, the more it will accelerate, while a heavier object will require more force to achieve the same acceleration. This law helps explain how objects move and interact in our world. For example, pushing a shopping cart will make it accelerate, but if the cart is full and heavier, it will require more effort to push it at the same speed.
