Use all your combined information from our stations, as well as the video clips and notes from the powerpoint, to do the best you can on this quiz. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. A chair will move by itself because of its inertia. Newton first published his work philsophiae naturalis principia mathematica mathematical principles of natural philosophy in 1687. Write a 1, 2 or 3 for each of the following to indicate whether its newton s 1st, 2nd or 3rd law. Ones body movement to the side when a car makes a sharp turn. If you push on a wall with a force of 30 newtons, the force acting on you is a. Aristotle 384 bc to 322 bc believed that the natural state of an object was to. Inertia was best explained by sir isaac newton in his first law of motion. Newtons first law of motion assumes that the forces acting on the object are balanced. That is as discussed in chapter 4, we have the following principle. Now\, after youve watched the video\, i want you to do one of the.
Newtons law of universal gravitation and laws of motion are named after sir isaac newton, an english physicist, mathematician, and astronomer. If the relative velocity between the two reference frames is constant, then the relative acceleration between the two. This is what causes the rocket to shoot up into the air. The first law states that a body at rest tends to stay at rest, and a body in motion tends to stay in motion at a constant speed in a straight line, unless acted upon. The focus of lesson 1 is newtons first law of motion sometimes referred to as the law of inertia. Newton s third law of motion describes the nature of a force as the result of a mutual and simultaneous interaction between an object and a second object in its surroundings. Restate newtons first law in terms of acceleration. Each of the items below is best represented by one of the newtons laws of motion. In the first calculation between the earth and the basketball, my m sub 1 will be the earths mass of 5. Newton s third law would tell us that when the rocket pushes out fire with a specific amount of force, the rocket will move in the opposite direction, but with the same amount of force. This interaction results in a simultaneously exerted push or.
Tightening of seat belts in a car when it stops quickly. Explain how each of newton s laws affects a game of tug of war. Newtons third law of motion describes the nature of a force as the result of a mutual and simultaneous interaction between an object and a second object in its surroundings. When an object is at rest or moving with constant velocity in an inertial frame of reference, the vector sum of all the forces acting on it must be zero. In the first calculation between the earth and the basketball, my m sub 1 will be the earth s mass of 5. Newtons first law of mojon is also known as the law of inertia.
