worked to create graphs of the plan without and with the catapult. The 300 comes from the initial height measured in feet and the -16 comes from (1/2) the acceleration of gravity in feet per second^2. The 20 with the catapult comes from the initial velocity of 20 feet per second. As you can see based on this graph the time the rock will hit the ground is roughly in 4.3 seconds. We can find the exact value by plugging in 0 for H (height)‚ 0 = -16t^2 + 300. We then subtract 300 from both sides and

If you want instant gratification‚ go suck on a lollipop‚ said Dr Cool while lecturing on velocities and acceleration. Although instant gratification has very little to do with the instantaneous speed‚ this quote is an example of his individualism in today’s instant gratification based society.

and the force the egg brings so that it lands safely. Background Obviously I built this device with some prior knowledge to physics and how to make this device successful. I have learned several equations about force‚ work‚ power‚ height‚ speed‚ velocity and a lot more. So with force‚ f=ma‚ then I can easily discern what the force of the egg will be. Also‚ since I know all of these things‚ than I can figure out all of the physics with just the equations. Also I learned‚ with these things‚ that if

CHAPTER 1: Introduction‚ Measurement‚ Estimating Answers to Questions 1. (a) Fundamental standards should be accessible‚ invariable‚ indestructible‚ and reproducible. A particular person’s foot would not be very accessible‚ since the person could not be at more than one place at a time. The standard would be somewhat invariable if the person were an adult‚ but even then‚ due to swelling or injury‚ the length of the standard foot could change. The standard would not be indestructible – the foot would

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

We varied both the accelerating force and the mass of the glider. We found that for a given force the acceleration of the glider was inversely proportional to the mass of the glider
