Newton's Laws

Lately, in class we have been learning about Newtons Three Laws of Motion. First law being that, 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. The second law is that the change in velocity (acceleration) with which an object moves is directly proportional to the magnitude of the force applied to the object and inversely proportional to the mass of the object. Lastly, the third law is that for every action there is an equal and opposite reaction. Friction, a major part with motion and force, is a conflict with force. It can either cause object to move at a faster pace or to slow down. Newton's laws are mostly used for measuring force, acceleration, and mass. These laws can be related into our daily lives such as a football game. The football will remain in the same spot if there is not friction, a football player to throw it, to cause it to move. It will continue moving if there is not friction, someone throwing it, to slow it down or make it speed up. My thoughts on this topic, is that this subject may be some what confusing, but once understood is very helpful in many situations related to your daily life.
