Newton's Laws of Motion

In science class we all have recently learned Newton's Three Laws of Motion. The creator of the magnificent laws is Isaac Newton. The first law of motion states, an object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force. For example, a desk will not move unless another force causes it to move, such as someone pushing or pulling it. The second law of motion states, that heavier objects require more force to move the same distance as lighter objects. Newton came up with a formula for finding force. Force equals mass times acceleration. For example, a small car, such as a Beetle VS a truck will require less fuel than the truck because it has a smaller mass than the truck which has a larger. The third law states, for every action there is an equal and opposite reaction. For example, when you jump up gravity pulls you down. These are Newton's three Laws of Motion.
