To illustrate the idea of this law, think of a shopping cart. When you go to a store, the empty cart is easier to push and does not require a large amount of force to move it. However, if you fill the cart with a lot of groceries, it requires a larger amount of force to help the cart accelerate.

Newton's Second Law- Force equals mass times acceleration.
Acceleration is directly proportional to the force applied. This means that if you push an object twice as hard, it will become twice as fast, increasing its speed. Also, the mass and acceleration are inversely proportion, meaning that if the mass is twice as much, and the same force is applied, the object will accelerate half as much.
