Newton's 3rd Law

274 Words2 Pages

Student Name¬¬_________________ Newton’s Third Law Use what you learned from the Force Plates investigation, and from the reading, to answer the following questions. 1. Before you started the Force Plates investigation, two strings were attached to a spring scale. Recall that a mass of 250 grams pulled on each side of the spring scale. Use what you have learned to explain why the spring scale read 250 grams rather than 500 grams. 2. In the top picture (on the right), Robert is pulling upon a rope that is attached to a wall. In the bottom picture, Robert is pulling upon a rope that is attached to an elephant. In each case, the force scale reads 500 Newton. In which case does Robert apply the greater force? Explain your response. 3. While

    The purpose of the lab is to acquire the percent composition of zinc and copper. The procedure included obtaining a post 1983 penny and washing it with soap and water. Using a triangular file, we made an X on the penny. Then, we cleaned the top and bottom of the penny with steel wool until it was shiny. We rinsed the penny in acetone and dried it with paper towel.

    Using the data provided in each one of these tests it can be assumed that one has done the steps to be able to determine the magnitude and orientation of the charges of the tape in each test, thus, allowing them to apply the same principle to any object they so desired. Their results would line up with the following; that if the two pieces of tape are torn from the same 40 centimeter strip then the tops of both pieces of tape would be positive and the bottoms of both pieces of tape would be negative and that if they would double the tape the attraction or repulsion in general would lower due to the increased density. Their data would also show that two pieces of tape ripped from each other would result in one piece being entirely positive and the other being entirely negative, they would also be able to state that the orientation of how the tape is paired up doesn’t matter.

    After I rinsed the copper I transferred it to a watch glass that had been baked for 20 minutes so it would not contain any liquid so as to not counteract the experiment. After I put the copper on this watch glass I baked the copper in the oven for 20 minutes so there would be no liquid left in that to mess up the mass. After 20 minutes I removed the watch glass with the copper in it and weighed itm making sure to weigh the watch glass

    For this part of the course we will apply Newton’s Law in one dimension at a time only. We will generally use the Cartesian subscripts “x” or “y” to indicate the relevant dimension we are considering. For example when we want to talk about the component of the net force in the x-direction, we represent this as the vector component Fx. Note that we never put little arrows on components.

  • Goldfish Metabolism Experiment

    1468 Words  | 6 Pages

    Introduction Metabolism is the sum of all anabolic and catabolic reactions within a living organism to sustain life. The energy required to perform these reactions is provided by oxygen in the form of ATP, therefore the oxygen consumption rate can be measured to determine the metabolic rate. Since oxygen is obtained through respiration, the efficiency of an organism’s respiratory system affects its metabolism. Previous studies have shown that caffeine affects the human respiratory center and occasionally dilates bronchus. It can thus stimulate human respiration and increase the metabolic rate (Haggins et al, 1915).

A question that is presented to the Force in Star Wars is “Is the Force a contact or field force?” The Force itself is surrounded everywhere in the Star Wars Universe, the factor that the Force is a power that is controlled by the Force user itself allows it to be controlled without any physical touch. Being Force sensitive, additionally, allows Force sensitive user to use the Force in certain instances, such as trying to reach for a lightsaber that is across the room. Newton’s

    Newton’s Third Law: - ‘For every reaction, there is an equal and opposite reaction’ - (Hall, 2015). If an object (Object A) exerts a force onto another object (Object B), Object B will exert the same force back, just in the opposite direction. A finger is exerting a force on to the wall. According to Newton’s Third Law of Motion, the wall should be exerting the same amount of force, just in the opposite direction, to the finger.

  • Newton's 3 Laws

    Newton’s law has 3 laws including the first one that states, an object that is at rest, or one that is moving at a certain velocity in a certain direction, will remain this way until an outside force acts upon another object also known as inertia. The second law includes an object's movement is directly relative to the force causing it, and inversely relative to the mass of the object. Then, the third laws says that an object for every action there an equal and opposite reaction. Newton’s first law is involved in skateboarding, which states that an objects in motion will remain in motion unless acted upon by an unbalanced force, also if a objects at rest will remain at rest unless acted upon by an unbalanced force. The key point is that all
