Intermolecular force

Propulsion is a force that pushes forward or drives and object forward. This concept can be seen in action with the use of a balloon powered car; this car demonstrates a type of propulsion system in which it produces thrust and potential energy and uses the kinetic energy that it will gain from the movement to push the car forward. The thrust is obtained from the balloon which applies Newton’s third of motion that states, “for every action, there is an equal and opposite reaction.” Specifically,…

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…

Forces are extremely important in a roller coaster, as they create the different sensations throughout the ride, and also help to hold you in your seat for safety. Forces on a roller coaster are measured in g's, which is how to measure gravity on the ride. The change of g's in different situations is what creates the different feelings and thrills you get on the coaster. When our marble is released at the top of the initial hill, energy is transferred from potential energy to kinetic energy.…

Conclusion The hypothesis was that extreme temperatures would affect the bounce height of a basketball. This hypothesis was accepted. The average bounce height for the regular basketball was seventy three and 3 tenths repeating. Sixty two and six tenths repeating was the average for the frozen basketball. The average was eighty-three and three tenths repeated for the heated basketball. We believe that these results are present because air molecules will expand in warmer temperatures and they…

Differences in thermoregulation patterns observed in the Monarch Butterfly, Danaus plexippus Many Lepidoptera species thermo-regulate using several patterns, physical and behavioral. These patterns are usually observed as movements from the shade and cooler areas to a place exposed to the sun as well as utilizing mechanical flight to generate heat. However, some species have intermediate behavioral patterns, often a mixture of basking and heat production, also known as endothermy (Kingsolver…

Goldberg machine’s task is to move the last piece on the chessboard to score checkmate by using the most complicated arrangement possible. In this Rube Goldberg machine, an outside source of energy is transferred through the machine when someone adds force to part of the machine therefore starting the “simple” task. The initial energy is transferred from through each object therefore creating a chain reaction and then resulting in moving the final chess piece. There are two main types of energy…

magnus effect and bernoulli principle occurring when the ball is kicked. The magnus effect is a force on a spinning ball moving through the air, taking some parts of the bernoulli principle. The bernoulli principle states that if the speed of a fluid around an object is slow then the pressure on the object…

person kicking the ball, the drag force and the magnus effect, and even the air pressure in the ball. It is harder than most people think. Next time you watch a soccer game, or play a soccer game, think about the science in the game. First, Newton’s Law’s are present when the ball is kicked. His first law, an object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force, shows that when one’s foot (the unbalanced force) collides with the ball, the…

Several organizational factors that cause stress are controlled by management and thus can be modified or changed. Strategies to consider include improved employee selection and job placement, training, realistic goal-setting, redesign of jobs, increased employee involvement, improved organizational communication, employee sabbaticals and corporate wellness programs. We know individuals with little experience or an external locus of control tend to be more prone to stress. Selection and…

This process of sealing was to cease all possibility of water touching the slurry and allowing for it to moisten. It was a necessary process. As for the steel frames that were going to be used for the building, Yamaski and the engineers agreed on bringing “kangaroo” cranes, which were cranes that would function with help of diesel motors and they were self powered. The reason for this was because since the goal for the buildings were to be the tallest building at their time back then, they…
