The physics concepts that were illustrated in our egg drop project were momentum and energy. In the project‚ we saw how momentum increases as a normal egg without anything to slow it down would crack. That was because the longer that the egg fell‚ the more momentum the egg gains. We also saw that by adding resistance during the fall‚ such as a plastic bag “parachute”‚ would slow down the egg enough so that it would not crack when it reached impact with the ground. The other concept that was discussed

Zach Hicks (Z1603274) Karen Richards Section F (0900 - 1150) 11/30/12 The Waiter Problem Solving Part A: Center of Mass in One Direction 1. Since the mass of the plate is a uniform‚ the center of mass is in the center of the plate. The plate has diameter d = 28 cm‚ thus the center of mass is 14 cm from the edge of the plate. In the lab‚ two scenarios will be analyzed; 1) when the glass is standing up‚ and 2) when the glass is laying on its side. When the glass is standing up‚ its mass

Introduction The purpose of this lab is to examine the motion of an electron‚ when it encounters a constant magnetic and electric field. We will also observe when the electric field and magnetic field will cancel each other out. This will lead to the electron having no net force acting upon it. By adjusting the values for the magnetic and electric fields‚ we will be able to check the different paths the electron follows. From this data we will be able to calculate the charge-to-mass ratio. Then

Bobby Wilson English 102 October 4‚ 2011 Death by Seatbelt The question of how imperative is it to enforce seatbelt laws in order to mitigate or reduce the number of deaths in the United States resulting from automotive accidents. The answer may somewhat obscure; the reason being because this issue has been an ongoing debate since 1849. “Motor vehicle crashes are the leading cause of death in the United States among persons aged 5–34 years” (vital signs: Nonfatal‚ motor vehicle‚ 1681)

An investigation into the specific heat capacity of a solid Introduction: In this experiment I investigated the specific heat capacity of brass and aluminium‚ in order to do this I arranged a series circuit with a heater‚ the heater would go inside the brass and aluminium and heat it for an amount of time in which I decided‚ I also used the voltmeter in parallel. This arrangement made me able to arrange the equation VIT= mcΔθ‚ since the electrical energy in would be equal to the mass times the

Explain why there is a point between two point masses at which the gravitational field strength is zero. Because gravitational fields of two masses are in opposite directions‚ so there is a point where it is zero What is meant by angular velocity The rate of change of the angular displacement of an object as it moves along curved path.

that secures a person in a car to prevent injury. A seatbelt contains a spring and spool‚ that work together to keep the belt snug while alowing movement‚ and a lock mechanism that is activated when a car stops or slows abrubtly‚ like in the event of a crash. The job of a seatbelt is to stop you with the car‚ without a seatbelt you would keep moving until acted upon by another force even though the car stopped. When the car stops abruptly‚ the seatbelt can extend the stopping distance and reduce the

The Importance of Seatbelts What happens if you forget to buckle your seatbelt just one time in the course of your day? The odds of something happening‚ that may or may not be detrimental to your health‚ is purely coincidental‚ or is it? Perhaps statistics‚ and a personal event in my life‚ can explain the importance of the seatbelt. Statistics show that more than forty thousand deaths‚ in the United States‚ are caused from car accidents each year. More than half of them could have been prevented
