action, there is an equal and opposite reaction.” This is done by using on board propellant which is then used to create thrust from a rocket engine, by ejecting thrust in the opposite direction to the rocket, it is propelled forwards at very high speeds. This propellant is either a liquid fuel or solid fuel (Braeunig, June 5th 2016). However, due to the rockets mass being more than 90% propellant, once they are launched, the empty rocket is then…

different cars. Daniel would build a lego car with small wheels and a long lever arm. And Taylor would build a record car with a small lever arm. These two cars turned out fair, but one had a better way of reacting to the forces on it.…

enough to significantly redirect the trajectory of the duck. This occurs because while the pellet is very light, it is moving at an incredibly high speed relative to the duck. All moving massive objects possess this property of momentum, a quantity proportional to the mass of the object times its velocity. Momentum is what allows objects to exert forces; it is the mechanism whereby two objects in a collision can influence one another. When two objects collide, they both enter the collision with…

It will encounter less water resistance as less of the hull is below the water. The secondary hypothesis is that the smaller the angle x, a surface is to the water, it will be able to skim and plane across the surface better, thus achieving greater speeds. The models of the boats will be further explained in the Methodology: Boat Design section. Experiment 1: Model A will have a velocity faster than that of Model B, as Model A will have the same mass spread over a larger area than Model B. This…

This law of motion stems off of the idea of force. Simply meaning that when you push off of something, the object that you are pushing off of is going to be pushed back due to the energy it takes to move an object. An example of this is hitting a golf ball with a club. The velocity of the ball is able to change due to the force of a golfer hitting the ball with its club. The more force a golfer uses on a ball, the faster the speed will become. Whereas a slight breeze from the wind would…

there is force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces. He hypothesized this theory while in the bath. Unfortunately his theory only covered fluid mechanics and didn’t elaborate completely on force. However he was one of the first scientists to discover buoyancy and the displacement of fluids. By 17th century Italian astronomer Galileo Galilei…

laws are here to understand why and what happens when using forces. Newton's laws have everything to do with forces and motion. There are three laws; the first being every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. The second is the relationship between an object's mass m, its acceleration a, and the applied force F is F = ma in this law the direction of the force vector is the same as the direction of the acceleration…

velocity, force, gravitational acceleration, free fall. I will explain the definitions of each concept, so readers will be able to get real meaning as to why these concepts consist of cheer leading. Gravity is the force that attracts a body toward the center of the earth, or toward any other physical body having mass. For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account. Therefore, cheerleading involves the force of…

the eggs. The egg ended up cracking slightly. Calculations Gravity equals 9.81 meters per second squared. The speed of the egg upon impact with the ground can be determined for the height of two meters. The egg was dropped from rest, so the initial velocity is zero. Final velocity squared equals initial velocity squared plus two times acceleration times delta distance, the final speed can be determined for the height of two meters. Vf^2=vi^2+2a(delta x) Vf^2=0m/s+2(2m)(9.81m/s^2)…
