Background Gravity/Freefall: Every object on the Earth’s surface is pulled towards the center of the earth by the force of Gravity. Gravity causes all objects in Freefall to accelerate downwards at the same rate, regardless of the object’s mass. On Earth, acceleration due to gravity is constant of 9.81m/s^2. Therefore on Earth when air resistance is not present, all objects fall at the same acceleration of 9.81m/s^2. However, on the planet Vela Rani, the value of acceleration due to gravity is…

of this experiment is to verify Newton’s 2nd Law of Motion. Introduction Newton’s 2nd Law states that when an external net force acts on an object, the acceleration of the object is proportional to the net force, and it also occurs in the same direction. The acceleration is also inversely proportional to the net force. Thus, the net force, which is the sum of all the forces acting on an object, is equal to the mass of the object multiplied by its acceleration. In this experiment, a cart with a…

Purpose: To investigate how acceleration of an object varies with an applied external force and the object’s total mass. Materials: Dynamics cart Track Pulley and clamp Retort stand Mass set Motion sensor Computer interface String Procedure: The apparatus was set up as demonstrated by the teacher. DataStudio software was opened using the Newton’s Second Law Experiment file found in the following location: I:4StudentsOUTRyanGrade 11 PhysicsExperiment FilesNewton’s…

Homework has several benefits and is important to a child’s success. Specifically, homework can be beneficial to a student’s academic achievements. The use of daily homework assignments can help students better obtain information which has previously been taught. A student who is introduced to an idea during class, then given an assignment, allows them to practice and grasp a better understanding of the concept. The aid provided from homework then opens up more time for further learning in the…

This statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. Newton's Third law of motion states that for every action force, there is a reaction force that is equal in strength and opposite in direction. The catapult arm is pushing up on the elastic bands with a lot of force, but my hand is pushing back, in the opposite direction, making the catapult…

Bouncing. Up, down, up, down. Right, left, right, left. Strangely, I remember this routine from the first eighteen months of my life very clearly. Every day my mother would strap my car seat to her back and carry me over seven miles to my daycare center. She would then trek even farther to work a full-time job, after which she would attend night classes at a local community college. Emboldened by a better life for the two of us, she overcame her pride and conquered every excuse. From my mother,…

1.1. Mechanical properties of CP/CNF and CP/CNF/ZIF-67 1.1.1. Stress–strain curves The stress–strain curves and the effects of CNF dosage on the tensile strength, elastic modulus, and elongation at break of CP/CNF and CP/CNF/ZIF-67 are shown in Fig. 3 and Tables S1–S4. As shown in Fig. 3(A) and Table S1, the tensile strength, elastic modulus, and elongation at break of neat CP is 7.37 MPa, 996 MPa, and 3.07%, respectively. After coating and crosslinking with CNFs, the mechanical properties of…

In this study, the Jumbo hopper (JH) barge is selected as a striking vessel. Also, the finite element models of impacted piers in isolated and multiple-pier cases including three piers and two spans are developed in LS-DYNA25 according to available characteristics in Consolazio et al.3 Fig. 1 shows the bow and non-bow (stern) portions of JH barge developed in LS-DYNA according to properties as given in AASHTO provisions.2 The bow portion of the barge contains the impact zone with outer plates…

In our society today, power, work discipline, and maximization of productivity has changed over time. The definition of work has changed from the time of feudalism to capitalism. Feudalism is described when serf and peasants offer their best harvest to feudal lord for protection. While capitalism, is defined as a means of production that is privately owned and used for profit consumption. From the definitions, it is evident that agriculture existed in the period of feudalism and production of…

If the mass of an object is held constant, increasing force will increase acceleration. If the force on an object remains constant, increasing mass will decrease acceleration” (How Newton’s Laws of Motion Work). Newton equated forces so that he could differentiate the change in momentum per unit time. Momentum is a characteristic involving a moving body using the product of the body’s mass and…
