able to put an addition onto one of my designs which gave me confidence in its ability to protect that precious egg. I will explain why my design worked so well in respect to impulse‚ air resistance‚ and stability. First‚ I will discuss impulse. Impulse is a force acting briefly on a body and producing a finite change of momentum. My design experienced this when it hit the ground. It does not matter how long force is on the object‚ it causes the same acceleration. To account for this‚ I made sure that

the scene. Cause of death? Disobeying the laws of physics. "Suppose the cars collide head-on and bounce off each other at 4.0 meters per second (9 miles per hour). The collision will change both cars’ momentum. But‚ because no force from outside the system has acted on the cars‚ their total momentum remains zero"(DiscoverySchool.com). Back to my example‚ although both cars were going the same speed‚ one driver lived while the other died. While this may seem like driver A was wearing his lucky tie

pressure is to use the pressure to accelerate the fluid at high velocity in a jet. The jet is directed on the vanes of a turbine wheel‚ which is rotated by the force generated on the vanes due to the momentum change or impulse which takes place as the jet strikes the vanes. Water turbines working on this impulse principle have been constructed with outputs of the order of 100‚000 kW and with efficiencies greater than 90%. There are mainly two objectives for this experiment‚ first of which is to measure

The impact of jet experiment is to demonstrate and verify the integral momentum equation.[1]. In lay man terms‚ it’s another way to understand fluid pressure by using the pressure to accelerate the fluid to a plate by a high velocity in a jet which in result will generate force due to impulse. The graph will show forces against momentum with different design plates. This experiment helps us to understand about fluid pressure also gives us a better understanding about fluid related machines.

Momentum & Energy Extra Study Questions Short Answer 1. What is the momentum of a 1000 kg car moving at 15 m/s [E]? 2. Calculate the momentum of each of the following objects. (a) a 0.50 kg ball thrown upward with a velocity of 30 m/s (b) a 2000 kg railway car moving south at 10 m/s (c) an electron of mass 9.1 × 10–31 kg‚ moving at a velocity of 1.0 × 107 m/s (d) the Earth‚ of mass 6.0 × 1024 kg‚ moving along its solar orbit with a velocity of 3.0 × 104 m/s 3. The momentum of a 7.3 kg shot is 22

different ways. It is actually hard to not think about the game of softball without some physics in mind. Specifically‚ the ideas of momentum and energy helps define the way softball works and why it works. Momentum Running: When running the bases in softball‚ there is a lot more to it then the average person would think. While we run the bases‚ we are changing our momentum by applying more force‚ the force of friction‚ onto the ground which causes more force exerted on us because of Newton’s 3rd law

The Egg-Drop Device Process The process of dropping an egg is more complex than a normal person would believe. The egg-dropping process requires knowledge of history‚ engineering‚ and mathematics and physics. To fully understand how an egg drops‚ the knowledge of the history of physics‚ the engineering behind a device‚ and the mathematics and physics of free-fall is needed. Classic physics originates in Ancient Greece. The theories Thales‚ the first physicist‚ designs gives the discipline of physics
