A lever is a rigid bar that rest on a pivot that is a used to help move heavy things or firmly fixed load with one end when pressure is applied to the other end. An inclined plane is a flat surface tilted at an angle with one end raised higher than the other which is used as an aid to raise or lower something. A wedge is a piece of wood, metal or something else where one end is thicker than the other which is tapered to a thinner end. It is driven in between two objects or parts of an object to secure or separate the object. A trebuchet is a machine that was used in the medieval siege warfare for hurling large stones or other missiles.
Write the goal of the labs on levers and pulleys or the question you tried to answer. Answer: To see how changing the relative position of the fulcrum affects the effort force required to lift an object. (3 points) |Score | | | 2. Which observations, experiences, or
An Atwood machine has two weights connected by a rope that passes over a pulley. As one weight moves down, the other will be pulled up. To begin, check that Mass A is 2.0 kg and Mass B is 3.0 kg. 1. Which mass do you think will move down?
The top part of the trigger shaped like a triangle while the bottom of the trigger shaped like a circular button. The trigger also allows this umbrella to be semi-automatic designed, since the umbrella can open automatically when pushed the circular button of the trigger. Figure 3: Trigger of the Saiveina Auto Open Straight Strong Umbrella 1.3. Ferrule Ferrule located at the end of the shaft and is made of metal. Its purpose is to reinforce the stability of the canopy and open cap on the shaft.
The middle layer is a group of laser beams. And the inner layer is nanotubes that protect structures from laser beams. Later he argues the lasers will destroy objects, which the lasers will go that get through the force field. To fix that problem Kaku thinks that the force field needs to have photochromatics. Then Kaku states that force fields can do more than deflecting laser beams because it can levitate objects by the use of magnetic force fields.
AQA GCSE Physics New Unit 2 Summary Notes Physics Unit 2 Revision (Higher tier) Forces Forced act in pairs. When 2 forces interact they are equal and opposite in direction e.g. a person exerts a force on the chair but the chair applies an equal force upwards on the person, a reaction force. Weight is also a force measured in newtons. Don’t confuse mass and weight as mass is actually the amount of ‘stuff’ that makes up an object measured in kilograms.
Medieval battering ram Good evening . Today I will be presenting and talking to you about the medieval battering ram and its significance in the third crusade. The battering ram was one of the most famous medieval weapons. It is the oldest ever siege engine and it was associated in Viking raids and siege warfare. It was used to knock down the gates and walls of medieval towns, castles and fortresses and could also be a part of a siege tower.
One reason our armed forces is the greatest, is the technology we have in our weapons. The FGM-148 Javelin is an anti-tank guided missile, more commonly called the “Javelin.” The Javelin is a fire-and-forget type of missile that locks onto its target before it gets fired with its automatic self-guidance. The missile attacks armored vehicles, mostly tanks from the top, where the armor is usually thinner. Unless it is commanded to take a “direct-attack,” which would get used when fired against buildings. The Javelin has a peak altitude
Three key biomechanics lower body mechanics, creating torque and turning it into speed and snapping the stick. Whether shooting the ball left handed or right handed, you want lead knee extension. This causes friction with the lower body against the ground, which will press back with equal force and you are essentially, transferring energy from the ground up through your body and into the core of your body which then spreads to your shoulders and arms. The stabilizing muscles used behind shooting a lacrosse stick, are your shoulders and arms. The further an object is from its axis of rotation, the further its linear speed.
Procedure 3: The Compound Pendulum The aim of this experiment is to determine the value of the acceleration due to gravity by measuring the period of oscillation of the pendulum when suspended from different distances from its centre of mass. A pendulum consisting of any swinging rigid body which is free to rotate about a fixed horizontal axis is called a compound pendulum. This experiment had to be carried out at Glasgow University as the required equipment was not available at school. Procedure 1) The pendulum was balanced on a large brass knife edge to determine the position of the centre of mass of the pendulum. 2) The larger moveable knife edge was then clamped to the pendulum, at a small distance (1cm) above the centre of mass.
