When a 0.067 kg metal ball was dropped from rest, the average acceleration due to gravity (g) was 7.33 m/s2(Appendix A Table 1) and the time was recorded as well as the displacement. The kinematic equation of motion for displacement, g=2(x-vot) /t2(Appendix A, figure 1), was used to solve for acceleration. The variable g represents the acceleration of gravity in free fall, x represents the total distance traveled by the ball, t represents time, and vo represents the initial velocity of the ball.

Introduction The purpose of this lab was to determine the relation between acceleration and net force with a constant net mass, and acceleration and net mass with a constant net force. For this lab, Newton’s Second Law was used as the basis for testing the relationship of the preceding. An equation was derived to determine the net force of the system. Equations 2-9 explain the derivation of the net force equation used in the calculations of the lab. The acceleration was determined for both graphs by

An experiment was set up with the goal to prove a hypothesis created, which stated that the mass of a marble would not have any effect in the acceleration of that specific marble as it moves down a ramp. During the testing of the hypothesis, the data collected demonstrated that the acceleration of three different marbles with different masses were nearly identical, which reinforced and proved the hypothesis. Acceleration is the rate at which the velocity of an object changes, and velocity is the

In our experiment the question we were trying to answer was “Does a physical change, change the mass of an object”. This means that when you take a tablet or clay and you crush it or alter the shape of it and it does not weigh the same after then the weight of the object did change and that would answer your question. When a physical change occurs it is not forming a new object it is just changing the way it looks or changing a solid to a liquid such as ice melting. During our experiment we took

to another, but the total amount of energy never changes. In this lab, roller coasters were constructed out of foam tubes to show the transformations of energy. Other variables that were identified during the lab were the speed of the coaster, the forces of motion and potential and kinetic energy. In this lab, a roller coaster was constructed using 3 - 1.83 meter foam tubes as a track (totaling in 5.49 meters), one marble (any type), masking tape, a stopwatch and a meter stick. In the roller coaster

stretch at all. The elasticity of skin actually has some degree of elasticity, but not much. Also, the temperature of the joint and associated tissues are musically more flexible at body temperatures that are 1 to 2 degrees higher than normal. Unlike normal humans, Elastigirl has an evolved extraordinary body system. There are many biological difficulties that Elastigirl would encounter if she did not have this body system, which would hindering her flexibility. As previously stated, she

Newton's Second law of motion proves that there is a relationship between Weight and Mass. Newton's second law of motion says that F(Force)=ma (mass x acceleration). Weight is a Force. It is due to gravitational force. Mass is measured in Kg or g and Weight is measured in Newtons as it is a Force. For example if you push a little boy on a swing with the same force you push an older man on a swing with the little boy will go higher. This is because he has less mass than the older man.

direction. The second objective was to win the mousetrap car competition against the other teams in the EG1003 class. The car came in second place in the competition. During the competition, the mousetrap acted as the propulsion source, which created force in order to move the vehicle. Similarly, in real-world applications, the internal combustion engines in automobiles release the fuel combustion into energy for movement once the combustion gases push the piston, allowing the rotation of the crankshaft

of the weight onto the front foot, a bent elbow to begin with, then the arm straightened out with wrist cocked, thus the force of the arm is being put into the wrist, hands, and then the racket. Extension of the arm and stepping forward means the muscles will be at optimum stretch (quadriceps, Biceps) allowing for optimum force. The racket then generates a large amount of force (from the range of motion) when contacting the ball. - Transfer and Conservation of Momentum - Momentum is conserved throughout

Purpose and Background: We used an air track and varying amounts of mass to determine the drag coefficient on an object. We used the equation FD=1/2CDpAV^2 to determine the drag coefficient. We also used FD=ma to determine FD, and we used V^2=Vi^2+2a(x-xi) to determine velocity. Since the cross-sectional area is remaining constant, the drag coefficient should also remain constant. We will measure the acceleration of the object and use that to determine velocity and drag coefficient. We will do this
