NEWTON'S FIRST LAW OF MOTION Newton's rst law of mo2on is also known as the LAW OF INERTIA Newton's rst law says that an object that IS NOT MOVING, or is at AT REST will stay at AT RESTAND an object that IS MOVING will keep moving with constant VELOCITY which means at the same SPEED and Inertia means resistance to change in motion. Determine the mass of a 300 pound (1330 N) football player. As with most problems, we next need to identify what needs to be determined and what is known or can be inferred from the problem as stated, that is, make a list of knowns and unknowns. Newton's first law of motion states that every object will remain at rest or in uniform motion in a straight line unless acted upon by an external force to change its motion. If we are solving for force and end up with units of millimeters per second, then we have made a mistake. endobj Once we have determined that Newtons laws of motion are involved (if the problem involves forces), it is particularly important to draw a careful sketch of the situation.
