Newton's Laws of Motion
Transcript of Newton's Laws of Motion
03/21/2013 Newton's First Law Newton's Second Law Newton's Third Law The force of an object is equal to its mass multiplied by its acceleration. (F=ma) This law states that the larger the mass of an object, or the more inertia it has, the harder it is to accelerate. An object will accelerate in the direction of the net force. For every action there is an equal and an opposite reaction. Furthermore, if one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction. An object in motion will stay in motion and an object at rest will stay at rest unless an unbalanced force acts upon it. Example # Example # Example # Example # Example # Citations: Explanation: Explanation Explanation: Example #1: Newton's first law states that an object at rest will stay at rest unless acted upon by an unbalanced force. The objects over the table cloth are not being pushed or pulled. Therefore, the objects will not move when the table cloth is removed out from under the objects.
Example #2: Newton's first law also states that an object in motion tends to stay in motion. The CO2 cars are traveling at the same speed until acted on by an unbalanced force. The towel at the end of the track happens to be the unbalanced force. If the cars were not acted on by a force, the cars would go forever. Example #2 "CO2 Car Racing." YouTube. YouTube, 28 May 2010.

Example #1: In this video, both objects are subjected to the same amount of force. Newton's second law is F=ma. Since the mass of the red ball is larger, and the force is the same, the red ball's acceleration is less. The yellow ball's acceleration was greater since it was lighter.
Example #2: This video is another example of Newton's second law. The girl with more mass is not pushed as far as the girl with the smaller mass. The acceleration of the girl with the smaller mass was greater because there was equal amount of force given to both, but since she weighed less, she went faster. Example #1: Newton's third law states that with an action, there is a opposite reaction. When the man throws the ball forward, that is the action force. The equal and opposite reaction force is when the man goes backwards on the cart.
Example #2: This video shows the ball coming out of a cannon. The ball going out of the barrel and flying forward is the action force. The cannon goes in the opposite direction due to Newton's Third Law and is known as the reaction force. This represents Newton's Third Law of Motion because the ball exerted a force on the cannon, and the cannon exerted an equal force in the opposite direction on the ball. Who is Isaac Newton? Sir Isaac Newton lived during the 1600s, and just like other scientists during this time period, he made beneficial contributions to the world around him. A portion of his helpful observations were about motion and have been supported by lots of data over time. His observation are what we now call Newton's Laws of Motion, which explain rest, constant motion, accelerated motion, and describes how balanced and unbalanced forces act to cause these states of motion.
