Air resistance force is a force exerted by air on an object traveling in air and it opposes the direction of motion. Tension force is a force transmitted through cables, wires and ropes and it is formed when a robe is being pulled from opposite sides. An object is sometimes in static equilibrium despite having forces of motion acting on it. This occurs when the sum of all forces adds up to 0. For instance, an object
The Second Law of Motion states “the force acting on an object is equal to the mass of that object times the acceleration. (F=MA). The Second Law of Motion describes what occurs to a massive body when it is acted upon by an external force. When a constant force acts on a massive body it causes to accelerate, and change its velocity, at a constant rate. If the object has been in motion, Jupiter Ed
Figure 15: First order plot for Optimized formula Higuchi model: In this model, graph is plotted between cumulative percent drug released Vs square root of time. Regression coefficient and slope values are calculated and interpreted. The regression coefficient value of this plot was found to be 0.972 and the slope was found to be 20.39 (figure 16). Figure 16: Higuchi plot for Optimized formula Koresmeyer peppas model: In this model, graph is plotted between log cumulative percent drug released Vs log time. Regression coefficient and slope values are calculated and interpreted.
The more the inertial mass of the body the more the force required to produce the same acceleration in it. We know from our common experience that more force is required to move a heavy vehicle (large mass) than a light one (small mass). In fact from Newton’s second law of motion (chapter two) we can show that the force ‘F’ required to produce an acceleration of ‘a’ in a body of mass ‘m’ is equal to ‘m’ times ‘a’. That is F = ma. When referring to the force applied by the earth on a body, the equation is F = mg, where g is called the acceleration due to gravity and the force is called the weight of the body.
Measurement of angle: When measuring the angle I used a protractor, which has inaccuracy about 5 degrees. It's a pretty big inaccuracy, but it should not prevent confirmation of the hypothesis. Centre arrows I put at the center of the protractor, as shown at the beginning of the work. The height of the protractor was regulated so that the arrowhead coincides with the central reference point in the protractor. And then with the help of my assistant, who used a different ruler to measure the angle of inclination to be as accurate as possible in our
As shown in Fig. A.2, the position vector on a continuous curve can be expressed as r(s) where s is the curve length parameter. When the curve is smooth enough, we can differentiate r(s) two times with s to obtain equation (A.17), where T is a unit vector pointing to the tangential direction of the curve and N is a unit vector which is perpendicular to T . ( 0)in equation (A.17) is called the curve curvature. Note that by this definition, N always points to the inner side of the curve as showing in Fig.
The detailed calculations being done can be seen in the tables 3, 4 and 5 of the appendix. Since the applied force and the displacement were on the same direction, the angle being used to calculate the average work done for both vertical and horizontal displacements in all trials, was zero. The average work done along the vertical displacement resulted to 18.933 J which was approximately 19 J, while the average work done along the horizontal displacement resulted to 3.495 J which was approximately 3.5
Each planet in the solar system interacts with the Sun via the same basic force and therefore undergoes a characteristic acceleration towards the Sun. Newton concluded that the solution to the problem of the nature of the gravitational force must be contained in the three empirical Laws of Planetary Motion discovered by Kepler few decades before.

To do this we will use the deflection equation =pa26EI(3l-a) solving for for each arm length (represented by l) and using E=15 and I=ab312where a=6.5 mm (thickness of meter stick/cantilever beam) and b=25.5 mm (width of meter stick/cantilever beam). The resulting points are: (50,2.94) (60,5.11) (70,8.14) (80,12.2) (90,17.4) We then graph these points and use Logger Pro to find the equation of the relationship. Figure 7 The equation given for this graph is g(x)= -.00000025x4-.0000933x3-.0078x2+.314x -
Then, we measure the concentration of shading between adjacent joint and joint. In other words, the slope of each portion, that is to perform the depth estimation. We assume that is above the subject at the light source. Position and its relationship to each joint was determined by the method “A, B and C”. In the same way as the estimate of the elbow or knee joint, we connect a line between the adjacent joint and joint.
