Purpose Determine the acceleration in a quick sprint. Question What would the participant’s acceleration be if he/she sprints forward in a positive direction? Hypothesis/Prediction When a person sprints forward‚ it means he/she speeds up. Consequently‚ the acceleration should be positive. When the velocity accelerates at a constant rate‚ the acceleration should remain constant. Therefore‚ if the participant is moving toward a positive direction and the speed increases‚ then the acceleration

1. The drawing shows three containers filled to the same height with the same fluid. In which container‚ if any‚ is the pressure at the bottom greatest? (a) Container A‚ because its bottom has the greatest surface area. (b) All three containers have the same pressure at the bottom. (c) Container A‚ because it has the greatest volume of fluid. (d) Container B‚ because it has the least volume of fluid. (e) Container C‚ because its bottom has the least surface area. 2. Three solid objects are floating

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

8.2 The World Communicates The wave model can be used to explain how current technologies transfer information. Describe the energy transformations required in one of the following: * Mobile Telephone Mobile telephones have built in microphones that changes sound waves ib Describe waves as a transfer of energy disturbance that may occur in one‚ two or three dimensions‚ depending on the nature of the wave and the medium Identify that mechanical waves require a medium for propagation

For my topic I chose to explain some of the physics involved in the sport of soccer. I chose soccer because I have played it my whole life and it is one of my favorite sports. I thought it would be interesting to learn about some of the physics involved in something that I do almost everyday and has been a big part of my life for as long as I can remember. My poster depicts the physics involved in kicking‚ the ball rolling across the field‚ and bending the ball. Kicking a soccer ball involves transferring

In this scene‚ the soccer ball was kicked by a player with a tremendous force. The Lightning hand Goalie (Forth Brother) stops the ball‚ but fly back because of the reaction force.This scene is an example of bad physics because it is unrealistic that a human can actually take off/fly after been hit by a soccer ball. Let us assume the following:-A soccer ball is usually weight 15 pounds = 0.4kg in Fifa games -We can’t simply calculate the velocity of the ball that the guy kicked in the movie. So

label the technologies on the photograph ii) Investigate three different technologies that have been implemented in cars or along roads to avoid or reduce the effect of collisions. In your investigation explain how the technology works in terms of physics laws and theories. 1. Crumple zone The purpose of a crumple zone is to increase the amount of time it takes for a car to come to a stop after being hit by an object. Crumple zones cause the force to be spread out over a long period of
