center of mass) , work (work is done on an object to set it in motion and give it speed), air resistance (A friction force that slows down the speed of an object), normal (perpendicular to surface and balances out the force of gravity) and contact force (One object comes in contact with another creating a force) and Newton's laws of motion (1. Velocity is constant if the sum of all forces acting on object is zero. 2. The sum of all

F; double fn, ft, vt; double friction; // compute total spring and gravity force XToxv(x, p, l, q, X); F = pl.m * g - sp.k * ((x - x0).norm() - sp.l0) * (x - x0).normalize(); // if in resting contact compute the friction force and support force fn = F * pl.n; // force component normal to the surface if(resting && fn < 0){ if(stopped){ // static friction ft = F * pl.tangent; // force component tangent to the surface friction = -Min(Abs(pl.mus * fn), Abs(ft))

important considering that it can be going 80 miles per hour. One can minimize air resistance by reducing the projected frontal area and going into a crouch position with legs and arms close to the body. Going into this position results in lower drag force and more speed. Another way to reduce air resistance is in the skiers clothing. It is most effective to wear form fitting clothing so that there is less wind getting caught by the clothes. One can minimize snow resistance simply by adjusting the way

(1). I awoke from a normal night’s dream-filled sleep in my normal, ever-so-drab bedroom. I ate my normal breakfast of possibly burnt toast and bacon. I put on normal clothes that totally weren’t on the floor from the prior week.... I used normal toothpaste that left my breath fresh and minty. I found some normal, albeit dusty, socks, and tied my normal high tops in normal triple knots. I went to school on a normal dirty school bus with the normal annoying people doing their normal thing - studying

Catastrophes and disasters occur frequently and indiscriminately. From acts of terror to acts of god, our species has witnessed immense loss of life with plenty of opportunity to prevent it. None is truer than the disaster of the Savar building (Rana Plaza) collapse in April 2013 in Dhaka, Bangladesh which resulted in the death toll upward of 1,053. At Rana plaza, corporate greed, corrupt government, and exploitation of the poor combined to allow for the deadliest garment factory massacre in history

Velocity Scenario 1 The two forces acting on the car when it turns a circular path are centripetal force, FCP , and friction, Ff . As mentioned in Relevant Physics Topics, the direction of friction opposes the direction of motion, which, in this scenario, is centripetal force, and because centripetal force directs towards the center of the circle, friction directs outside of the circle (Madden et al., 2001). To calculate the safe cornering speed on a level road, centripetal force has to equal friction

a fighter jet all this knowledge will come into your mind every time you go to fly or fly your missions. When you are flying a fighter jet in the Navy there are certain aspects that you should be aware of. For example fighter jets can “stall” or in other words the engine could stop running. “A stall occur at the angle of attack, at which point the airflow over the wing becomes chaotic and the wings can no longer produce sufficient lift to counteract weight”. As the airfoil approaches the stalling

stretching in the legs, the greater the power generated as the legs are extended(biomechanics). As the tennis player extends their legs this elastic potential energy is converted to kinetic energy and a ground reaction force is generated. This ground reaction force can also be called normal force. As the player extends their legs the tennis court ground in contact with their feet is compressed

desires of a man as well. “Both males and females, she seems to tell us, are complex creatures whom have no choice but to discover their passion, in spite of risks, confusion, and guilt. (Bloom 81)”. According to Per Seyersted, “sex in this story is a force as strong, inevitable, and natural as the Louisiana storm which ignites it” (Koloski 145). She observes sex as being a natural thing that cannot be avoided in or outside of wedlock (Koloski 147). She writes as if this affair was unavoidable to the

obtained when the force applied to an object varies. Thus, different hanging masses will be hitched to a cart to observe the impact on the acceleration. As the mass of the cart will remain the same, the purpose of the procedure is to verify the relation between the applied force on an object and its acceleration which is, according to Isaac Newton, F=ma. The results of this experiment are useful because it has an impact on all calculations about dynamic motion. For instance, the force exerted by a car’s
