Velocity

Momentum; it is the product of the mass and velocity of an object. “P” is the 3D vector stating the object’s momentum in 3 directions of 3D space. Where “V” is the 3D velocity vector giving the object’s rate of movement in every direction it goes. “M” is the object’s mass. The second factor is air resistance also known as drag, is the forces that are in resistance to the motion of an object through the air. Drag forces act the exact opposite to the coming flow velocity. So basically it pushes…

Magnets create magnetic fields, which can attract or repel metal objects. Magnets are utilized in motors, circuits, compasses, and can be used in many other applications. They are also used in something called the Gauss Rifle, which can use magnets to launch a projectile at high speed. It is made up of one or more magnet stages, which consists of a magnet and two ball bearings on one side. The number of magnet stages can determine how fast or how slow the projectile can go. It should be noted…

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 velocity. To determine the differential change, Newton created differential calculus and created an original equation. That equation…

Building bottle rockets can be a fun and learning experience, as many students at UCAS found out. There were many things to test, and many interesting aspects of the rocket. Three main features of the “Mission to Mars” are how to construct the rocket, rocket performance, and physics of the rocket. When these items are viewed, it is evident that students can see the effects of physics in real life problems. And by doing so become more intelligent as teenagers want to learn more, and have fun…

component from the onset of the stretch in both extensor and flexor muscles (Nardone & Schieppati, 2008). In the experiment it did slow the action potential velocity down to close to the same value as when the tendon was struck relaxed. As the stimulus on the tendons increases in amplitude it was shown the that action potentials had a faster velocity speed but did not change the amplitude of the action…

300 0.50 157.1 43.7 300 0.40 125.7 50.0 374 0.40 125.7 60.0 544 Next, the effect of solidity σ on the water turbine characteristics was measured. Figure 2.1 shows a comparative analysis of torque characteristics for different solidity ratios at velocity 1.0 m/s, performed by Shionoet. al(2002). Figure 2.1: Torque characteristics (v=1m/s, ɸ=43.7° ) Figure2.1 reveals that the larger σis, the more the peak value of generated torque becomes, and then the peak value is shifted to lower λ. This is…

The photo on the right shows a medical technician using an ultrasound machine to diagnose appendicitis to a patient, without the use of x-rays. The ultrasound imaging technique involves using high frequency sound waves and their echoes. The machine transmits high-frequency sound pulses into the patient’s body using a probe. In the image, the technician presses and moves the probe along the patient’s body. This photo was taken in the St. Louis Children’s Hospital, and obtained from *. In terms…

Test #2 Correction Question 2. Diagnosis Phase: When I first read the question, it reminded me of my multivariable calculus first class session where my professor used an example of a plane being landed in windy weather, to teach us a concept of vectors. Initially, I began to picture the scenario of a plane flying under consideration of wind being involved instead of looking at the numbers. Afterward, I drew the free body diagram of how the problem looked as using numbers and direction. Since…

the change in velocity and in the F=ma equation, the F stands for net force. For example, if a car was traveling at a constant velocity, it would still have forces such as gravity, friction, and normal force acting on it. 2. Only one force acts on an object. Can the object have zero acceleration? Can it have zero velocity? Explain. a. If only one force acts on the object, then the net force cannot be zero. Therefore, it cannot have zero acceleration. The object can have zero velocity for an…
