Motion sickness

Grant Alexander Pd#6 11 November 2016 Trebuchet Engineering A trebuchet is a machine used in medieval siege warfare for hurling large stones or other missiles. How this machine works is not to complex but is also fascinating. The object that is being shot is held in the sling, which is on a launch trough whose job is to make sure the shot is straight. Also the trough is there to prevent the sling getting caught in the framework of the trebuchet. When putting the arm of the trebuchet down,…

scientists and mathematicians as a parabola, and objects that fly in the shape of a parabola are said to be in parabolic motion. A projectiles motion can be broken up into two separate pieces, horizontal and vertical motion. These two motions act independently of each other meaning no matter how much one of them changes the other will be unaffected. While in parabolic motion the only motion…

Students will investigate relationship between force, mass, and the motion of objects. 2. How does your rubber band car show Newton’s 1st Law of Motion? The first law states an object will stay at rest until acted upon unbalanced force. The car is at rest until the rubber band is twirl all on the stick. This mean a force has to be added for the rubber-band car to move. 3. How does your rubber band car show Newton’s 2nd Law of Motion? The second law is Force X Mass= Acceleration. The force is…

The purpose of the experiment was to determine how altering the amount of mass in a makeshift rocket will affect its distance. Our hypothesis stated that when more mass is added to the rocket, its distance will also increase. To investigate this theory, we conducted an experiment in which the mass of the rocket would be changed using differentiating amounts of water. To measure the height of the bottle rocket, we took rope and attached it to the girth of the liter bottle to determine how high…

flying. However, because there is no air in space, there is no air resistance, meaning there is nothing pushing against the ships so that they could fly. In Newton’s first law, he states that “Every body perseveres in its state of rest, or uniform of motion in a right line, unless it is compelled to change that state by forces impresses thereon” It is the law of inertia. This scene goes against this law because there is nothing pushing on the ship to make it move. So the movie implies that…

The foot and ground exert an equal and opposite force on each other. This is known as the ground reaction force.12 The position and acceleration of the runner's center of mass regulates the direction and magnitude of the ground reaction force. For instance, a runner sprinting from a standstill. Throughout the initial phase of acceleration, the body is inclined forward and therefore the center of gravity falls in front of the contact surface. After many gait cycles, the runner reaches top speed…

Motion Down an Inclined Plane Andrew Park Ms. Jatindranauth SPH 3U7-A September 28, 2017  Introduction The purpose of this lab is to determine the effect displacement has on the final velocity of a trolley on an inclined ramp. What is hypothesized is that as the distance the trolley rolls down decreases, the velocity should decrease with it. Also, because the trolley should uniformly accelerate, the standard equations of motion can be used to calculate many different variables (one such being…

Objective: The purpose of this lab was to examine Newton 's second law by observing the relationship between force and acceleration in a friction-free environment and to illustrate the concept of mass. The experiment was conducted in such a way to reduce friction. In order to simulate this environment an air-cushioned track was set-up for the glider to ride on a pocket of air without being in contact with the metal track. In addition, this glider will have masses attached to it as well as a…

put the opposition under pressure. In biomechanics there are a number of focuses that need to be discussed, such as Newton’s three laws of motion and the centre of…

enemy who was on the other side (Farrell, 2006). The trebuchet uses Isaac Newton’s laws which are; The greater the mass of the object being accelerated the greater the amount of force needed to accelerate the object and (Pearson science ,2012). The motion of the projectile launched is parabolic and is influenced by factors such as the mass of the counter weight, the length of the pivot arm…
