Recently in class we learned about Sir Isaac Newton and the three laws he developed about the states on motion. These laws show how motion is caused by a force or forces. The first law of motion states that an object at rest will always remain at rest and an object in motion will remain in motion at constant velocity unless acted upon by an unbalanced force. Sir Isaac called "the tendency to remain in motion of rest" inertia. The first laws also tells us that acceleration and force are related because if an object wants to accelerate a force needs to push it. An example of this could be if you a throw a bowling ball with the same force you throw a tennis ball, the tennis ball will go farther because it has less mass.
The second law of motion talks about how acceleration and force are related. It shows how more heavier objects or objects with more mass move at the same distance as lighter objects or objects with less mass. The formula that Isaac come with for finding out the force is force= mass multiplied by acceleration. For example, if you are trying to push a car, which will cause it to accelerate, and then you push 5 times harder then how much the car move will be 5 times faster.
The third law of motion states that for every action, there is an equal and opposite reaction. An easier way to understand this is that all forces come in pairs. An example of the third law of motion is when a space shuttle takes off into space because it pushs downward but goes upward.
