Free-Fall Acceleration Introduction Galileo Galilei (1564-1642)‚ the man first accredited with the correct notion of free-fall with uniform acceleration‚ stated that ’if one were to remove entirely the resistance of the medium‚ all materials would descend with equal speed.’ Today‚ this statement holds true for all objects in free-fall near the Earth’s surface. The purpose of this experiment is to verify Galileo’s assertion that acceleration is constant. In addition‚ the magnitude of acceleration will

Case Study: Toyota Acceleration Problem 1) For the case study‚ our group‚ The Socratic Triads‚ we have chosen to analysis the ethical issues that are related to the Toyota acceleration problem. The Toyota acceleration problem first came to the light in the media around late 2009. The acceleration pedal of certain models of Toyotas and Lexus were unintendedly accelerating without the driver’s foot on the pedal. It has been reported that the acceleration pedal has been malfunctioning as early as 2003

Free fall and the acceleration due to gravity Problem/Question: How do you measure the acceleration of a falling object? Hypothesis: by measuring velocities of a falling ball then applying the data into equations numerous times‚ the results should approach to the acceleration. Variables: A: Independent Velocity B:Dependant Acceleration C:Constant Distance (photo gates) Materials: Photo gates‚ Clay ball‚ Photo gates machine.

Motion-Force and Acceleration The Big Idea: An object accelerates when a net force acts on it. 6.1 Force Causes Acceleration • Unbalanced forces acting on an object cause the object to accelerate. • The combination of foces acting on an object is net force; acceleration depends in net force. • Doubling the force on an object doubles its acceleration. • An object’s acceleration is directly proportional to the net force acting on it. 6.2 Mass Resists Acceleration •

accepted value of acceleration due to gravity is . In this activity‚ an air-cart’s motion will be graphically analyzed. A mass will be attached to the air-cart by a string and hung over pulley with the other end attached to an air-cart resting on a frictionless surface. The study of the motion of the system of masses will be used to determine the velocity of the masses from an analysis of the displacement versus time data. This velocity will then be used to calculate the acceleration of the system

Investigating the Incline of Marijuana Usage among Adolescents Dashaun Fails COMM/112 2/12/2013 Karen Hamilton Within the last several years there has been a slight increase of marijuana usage nationally amongst adolescents ranging from the ages of eleven to eighteen. Youth tend to be easily pressured or influenced into smoking marijuana by entertainment such as movies and music‚ as well as friends and family members that condone the habit. Since it is nearly impossible to overdose on marijuana

Physics 211 Experiment 1: Free Fall - Determining the acceleration of gravity Prior to Lab: Derive the numbered equations (Equations 1‚ 2 and 3) in the lab instructions using the definitions of velocity and acceleration (a=dv/dt and v=dy/dt). Object: The object of this experiment is to determine the value of the acceleration of gravity by measuring the rate of acceleration of a freely falling object. In addition‚ one will be able to compare theory with experiment for constantly accelerated
