Conservation of mass

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,…

Problem: how does the angle of trajectory effect the horizontal distance of a bottle rocket Background research: When an object is in the air and has no forces acting on it other than gravity it becomes a projectile. (Henderson, 1996) Gravity causes the projectile to accelerate toward the ground in a uniform arc like a rainbow does. this shape is known by 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…

The right to bear arms is a constitutional right, but what brand of firearms is all around best for the citizens of the United States of America to own and shoot? The brand Remington has been around for roughly 200 years and have specialized in the development of guns for the majority of their establishment and is considered America’s best gun brand by many, how do they do it? To every gun there are 3 key features and these are; safety, weight of the gun, and of course the reliability of the…

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 rubber band and the mass is the…

For task one My hypothesis was "If the forces on each side of the rope are equal, then the sum of forces will be zero. If we can determine the force each person on both sides of the rope, then we can determine if the sum of their forces will equal zero. " which was, correct. I know my hypothesis was correct because of the balanced force. A balanced force is when you have an equal amount of force on each side of an object when force is being exerted on it, it doesn't move because there is no…

Learning Experience number ( 2 ) 1- Arnold Dumbbell Press - raising the dumbbells as i rotate the palms of my hands , is the concentric motion. The second phase, as I lower the dumbbells back down, is the eccentric motion, . as i pause while the the dumbbels are at the top, is the isometric contraction. 2- Alternate Hammer Curl - as I curl the weight toward my shoulders, is the concentric motion. as I lower the weight back down, is the eccentric,motion. As the weight is held at the top of the…

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…

robot should have stayed in its state because there was no force acting on it. The ships are quite obviously in space, and because they are in space there is no gravity unless they are by a very large object that has a large mass. If they were by a very large object with a big mass, then it might be reasonable to say that the robots was being pulled by gravity towards the large object, but there was no large object to be seen. Therefore, it could not have been suddenly pulled away the way it…

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 and their center of mass then moves backward. A participant who tried to accelerate with their…

P1 – Task 1, M1 – Task 2, M2 – Task 3 Iodine Extraction Equipment:  Goggles  Fume cupboard  2X 250cmᶾ beaker  Filter funnel  Filter paper  Separating funnel  Bunsen burner  Tripod  Gauze Method: 1. Set up the equipment with the Bunsen burner and tripod on the heatproof mat with the gauze on top of the tripod. 2. Add the seaweed to the tin lid and place on top of the gauze (try not to use any ‘pods’ of seaweed as they pop when heated which could be dangerous). Light the Bunsen burner and…
