always trying to find new ways of killing each other and winning. Combat was getting more and more sophisticated and human force was not sufficient enough to conquer a castle or destroy a ship. That was the time when ancient engineers introduced siege warfare‚ when “simple yet complicated hurling machines that rely on the fundamentals of math and physics using levers‚ force torsion‚ tension‚ and traction” were brought to the battlefield. One of the most unique and destructive siege weapons was

the reaction forces are exerted like a simple nozzle when the fluid accelerated due to the changes in the cross sectional area. The kinetic energy of the fluid increases and since energy is conserved‚ the pressure of the fluid drops. This is meant that the pressure behind the fluid forces it through the nozzle causing it to speed up. The accelerated fluid in the direction of acceleration is required by force. Every force has an equal and opposite reaction so an equal and opposite force is exerted on

time (2.15 s) the heavier weight took to hit the bottom‚ to calculate the acceleration (0.36 m/s^2) of the Atwood machine. Once the acceleration was obtained‚ we used it to find the angular acceleration or alpha (2.12 rad/s^2) and moment of force(torque) of the Atwood machine‚ in which then we were finally able to calculate the moment of inertia for the Atwood machine. In comparing rotational dynamics and linear dynamics to vector dynamics‚ it varied in the fact that linear dynamics

determines how far the cars I made for my project will go. This illustrates how if the car doesn’t have enough kinetic energy the car won’t go very far. According to my research‚ If work‚ which transfers energy‚ is done on an object by applying a net force‚ the object speeds up and thereby gains kinetic energy(Kinetic Energy) which will make my car go further. This illustrates how if there is more potential energy than kinetic energy the car won’t go nearly as far as it could. According to my research

By utilizing key physics concepts‚ a dancer can improve by locating the center of balance and determining the force vectors of a Grande Jette jump. Maintaining a strong center of balance is one of the key principles of strong dance technique. Whether dancers are working to control their turns or maintaining a position while standing on their toes‚ they are always

To get the ball to fly the farthest distance possible‚ the kicker must be in contact with the ball for around 8 thousandths of a second‚ while providing over 1 ton of force to the ball over that time period. This is what is known in physics as an impulse‚ which is the force multiplied by the time the force is

During an experiment‚ there was a glass eye dropper placed into a bottle filled to the brim with water with the cap closed. The glass eye dropper floated in the bottle when the bottle was left alone. When the bottle was squeezed‚ however‚ the glass dropper sunk to the bottom. When the pressure was released from the bottle‚ the dropper floated back to the top of the bottle. The dropper floated at the top of the bottle when no pressure was applied‚ because the air inside the dropper was less dense

How Guns Work A gun is a weapon that uses the force of an explosive propellant to project a missile. Guns or firearms are classified by the diameter of the barrel opening. This is known as the calibre of the gun. Anything with a calibre up to and including . 60 calibre(0.6 inches) is known as a firearm. The precise origin of the gun is unknown‚ although they were in use by the early 14th century and were common place in Europe by mid-century. These early guns were nothing more than large
