Mass hysteria

of 100 grams was the controlled variable which means that it was held constant during the entire experiment. The mass was connected to the string which represents the independent variable since we varied the length of the string throughout the lab. We tied a loop on the string to hang it on the clamp so the weight was free to move. The string was very lightweight compared to the mass due to being able to come as close to the ideal of a massless string as possible. The dependent variable was…

Fig. 3(a), 3(b), 3(c), 3(d), 3(e), 3(f), 3(g), 3(h) & 3(i). Knee arthroplasty step by step simulation. The proximal tibia is shown in fig. 2(a) where the menus for adjusting the simulation is shown. In knee arthroplasty, virtual saw is used to cut the bones in the knee from front to back. This method of cutting enable the virtual saw to penetrated tibia and then femur part of the knee. The tracker is an interface that is attached to the surgical instrument to track the position and attitude of…

Investigation Hooke’s Law AIM: To investigate how a spring behaves when a force of load stretches it. To figure out the relationship between the loads added to spring and the extension of spring. HYPOTHESIS: I think that as the load added to spring increases, the extension of the spring will increase. The relationship between them will be directly proportional. The formula of these two variables might be F=kx. F stands for the load added to spring, k is spring constant and x stands for…

Omar Alawad Math SL Mr. Sidat Stopping distance Introduction When driving on roads, drivers may see an obstacle ahead that requires them to apply brakes suddenly to stop. The distance covered by the car from the moment the driver applied brakes to the moment the car stops is called the stopping distance, which is also referred to as the braking distance. For a car travelling at an initial speed of , the stopping distance traveled by this car is given in the formula: The stopping…

In our lab, we had to do experiments to answer the following questions: Problems: Is the frictional force greater when an object is still (static) or sliding? 2) Does the surface area of contact between two surfaces affect the frictional force? 3) Does the type of surface (carpet vs. hard/smooth surface) affect sliding friction? 4) Does the force between two objects (weight) affect sliding friction? While doing this lab, we were able to answer the given questions and we were…

Experiment 3: Buoyancy Introduction Mass is described as the measure of the amount of matter contained in an object. On the other hand, weight is the measure of the force of gravity acting on the mass. Mass is measured in kilograms, while weight is measured in newtons. The density of an object is found by dividing the mass by the volume. Buoyancy is the upward force of a liquid which counters the weight of an immersed object. The theoretical buoyancy of an object can be calculated by using the…

Natural Forces Affecting the Driver In one or more complete sentences, explain how natural laws apply to the following scenarios: 1. How does inertia affect a person who is not wearing a seat-belt during a collision? The prison will continue going forward at the same speed as the car was before the collision until something stops them. 2. How does kinetic energy affect the stopping distance of a vehicle traveling at 30 mph compared to the same vehicle traveling at 60 mph? There is 2 twice the…

where potential energy is. Potential energy is the energy which results in position. Usually the most potential energy in a roller coaster is when it is about to start. The way that this type of energy is calculated and measured in P=MGH. M, being Mass, G being Gravity, which is always constant and is 9.81 N/kg and H being height of that point, and that is measure in…

tested was the ideal mass of the rocket. A lot of the rockets distance depends on the mass and the area. Another variable that had to be tested was how many fins to use based on the ideal mass for the rocket. In a rocket it is normally true that it will fly the farthest if the mass is closer to the front, and the surface area to the back, so that the center of mass and the center of pressure are as far apart as possible, but too many fins could cause a problem. Once the ideal mass and surface…

M1 locate the bones, joints, movement types and muscles used during a range of sporting activities: Example 1 – Andy Murray tennis serve. The Andy Murray serve begins with him lining up at a 45 degree angle to the baseline. His legs are a little more than body width apart with the left foot about 30 degrees off the line. This stance means that he will be using a big turn of the whole body to assist in providing some of the power to his serve. His arms are extended out in front. His left hand…
