Body mass index

means an increase in mass, which increases resistance to the object that is passing through it. Properties of the Fluid: Compressibility and Viscosity; as the object passes through a certain material the matter will be compressed such that the object may pass with ease. If it is non-compressible the air drag will increase thus denying the object maneuverability. Factors Affecting Lift: Object: Similar to drag, the objects shape and size all affect the lift. Obviously, mass is inversely…

This law is when a force is being put on an object but it isn't balanced nor equal. When Bennett pushes off the block he is no longer at rest therefore unbalanced forces are acting upon him. Bennett is the object and his mass compared to the block’s mass causes his acceleration to happen when he pushes off the block and into the air. There is also a friction force when he is positioning his feet on the block to move his feet kinetic friction is in action. In newtons 3rd law “ for every…

Second Law changed Physics. There are many equations and formulas that are important in physics because of what they imply or solve like E=mc^2, but Newton’s Second Law of motion has to be one of the most important. F=m(dv/dt)(Quote) F=ma Force = Mass x Acceleration (Newtons) With the use of this equation he proved that objects that are heavier fall at the same rate towards earth as objects that are lighter because the earth pulls them down with the same force. To put it in perspective a car…

Rube Goldberg Project For this Rube Goldberg project I am going to explain how my machine worked. My simple task was to pop a balloon. The item we used to pop the balloon was a mousetrap. I am going to go step by step through how I created my Rube Goldberg machine. First, we started out with a ramp that we dropped the ball on. That was our potential energy. Next, we had a ball drop down a tub at approximately 180°. That was mechanical energy. After that, the ball went through an elbow and…

Bouncy balls bounce because the material of the ball is extremely elastic and can convert kinetic energy from falling into potential energy and back into kinetic energy again with little loss of momentum. They are used in many classrooms because they can easily demonstrate conservation of momentum through a highly elastic collision. Like many things made out of rubber, bouncy balls have very high elasticity, meaning they rapidly return to their resting state after being stretched or squashed. If…

By finding the area underneath the velocity versus time graph and by adding up all the displacement intervals gave values near each other. This means that there are two ways to calculate displacement using a velocity versus time graph. Experimental Uncertanties There were several experimental uncertanties accountered in the accelerated motion lab. Firstly, the presence of air resistance. As the object traveled down the ramp increasing its velocity, air resistance increased which affected the…

Introduction: Hot packs work by dissolving a salt, such as calcium chloride, in water to create an exothermic reaction. When salts are dissolved in water it requires energy to break their bonds apart, but energy is also released when the ions are surrounded by the water molecules. If more energy is released than is required to break the bonds, the reaction will be exothermic and will produce heat. In hot packs the water is kept separate from the salt, and when it needs to be activated, they are…

the force of the object increases. In this case the propelling force is thrust. In order to increase thrust, the water must be expelled from the rocket at a fast rate. Secondly as the mass decreases, acceleration will increase due to the inverse proportions and because of the increasing Fnet. Therefore the rockets mass, must as minimal as possible, in order to have an increase in acceleration. Fnet = ma Newton’s Third Law of Motion – For every action there is an equal and opposite reaction.…

anything that has mass and takes up space where energy allows the ability to do work or have the ability to move or elicit change in matter. In other words, energy is a property of objects which can be transferred to other independent objects or be converted into different forms. It is described as “a system to perform work.” We have two different types of energy; kinetic and potential energy. Kinetic energy is the energy of motion. This allows work needed to accelerate a body of a given mass…

embodied the 14th century artistically. Guillaume de Machaut was born around 1300 somewhere near Réthel in the Champagne of France. The ordinary mass has come a long way since it was created. Guillaume de Machaut created the first polyphonic cycle by a single composer, Messe de Nostre Dame was revolutionary not only because it was the first polyphonic cycle of the mass by a single composer, but because of how he accomplished it. In order to discover what made Machaut so special one must analysis…
