Speed Force

Biomechanics refers to the “study of the action of external and internal forces on the living body, especially on the skeletal system” (Dictionary.com, 2015). By using biomechanics we can examine and find ways to successfully enhance performance, develop exercise programs and modify sporting techniques (Swedan, 2013). This paper will be analyzing and evaluating the athletic event of high jump. Biomechanics will be applied to critically examine the techniques used in high jump and improve upon…

the Earth. Kepler develops the three laws of planetary motion. Galileo discovers that the natural state of an object is either at rest or moving with a constant speed, for as long as no unbalanced forces are acting on the object. Galileo reasons that if friction and other forces were balanced, an object would continue along at constant speed. Galileo understands the concept of acceleration and motion of objects acted upon by…

Trajectory and applied force both have very much too do with our rocket lab. Trajectory affects how far the rocket will get beacuse trajectory is a curved path of an object that has been fired or thrown through the air. This affects the rocket beacuse the angle of the rocket that is launched at is part of trajectory and the rocket was launched off of an angled platform so this affetced how high the rocket went before coming down. Another part of trajectory is how gravity affects the objects…

(both initial and final), Acceleration, Displacement, and Time to find how fast the egg within the vessel will go when drop from the top of a rail in the back of the school. Initial Velocity will determine the speed the egg left its initial position, the final velocity will determine the speed of the egg before crashing, Time (in Second) will tell how long the egg was in the air, Acceleration will tell how fast it went, and Displacement will tell us how far it went. The project consist of an…

fluctuate in process of fatigue failure analysis. The last objective is using the stresses model to find the force is applied on the crank shaft. Sample Calculation: For collecting the data, a bicycle crank shaft is pedaled. In the sample calculation, a 1N for a crank angle of θ= 90 degree will be calculated. Strain Gage 2 Pedal Force = 1 N θ= 90 degree…

The acceleration of the object will increase as the force of the object increases. In this case the propelling force is thrust. In order to increase thrust, the water must be expelled from the rocket at a fast rate. Secondly as the mass decreases, acceleration will increase due to the inverse proportions and because of the increasing…

the apogee might be affected in a variety of ways, one being the weather. After the class found all of the data, it was compared and analyzed for any patterns. The rocket had different forces acting upon it during the flight stages. The first stage is ignition, (when the engine of the rocket ignites) the force acting upon the rocket is the thrust (push/propel) due to the electric launch controller which heated up. After the motor created thrust, it caused the rocket to lift-off (creates…

Isaac Newton’s Laws of Motion and Crumple Zones Crumple Zones design and function The crumple zone is the front and the rear of a motor vehicle that is designed to crumple without difficulty and to absorb the force of the impact in a crash. Crumple zones are also known as crush zones and they absorb energy in a crash so that it doesn’t transmit to the occupants as much. The zones are now made in cars to prevent death for occupants or serious injuries when in a crash. The front of the vehicle…

Sullivan Jackson Kachigan Physics 16 February, 2018 SAHC: SJ How Mass Effects Luge Luge is an unusual sport where the rider or riders on a sled-like device are barreling down an ice track at speeds up to 97 mph. Because of these tremendous speeds, one may think that the rider(s) must be light and nimble so they could glide through the course with ease. However, this is the complete opposite of reality and in the physics world, it makes complete sense. As you may have guessed, the…

are no forces acting on it? Explain. a. No, forces would still be acting on an object if its acceleration is zero. Acceleration is only 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…
