again. This change in momentum is the impulse. After the cornea has rebounded after being flattened‚ it won’t come to a complete stop‚ it will vibrate back and forth. This loss in momentum captured by the tonometer can be accounted for using the following method: 1. m1iv1i + m2iv2i = m1Fv1f + m1fv2f (momentum in number one) m1= mass rod ‚ m2=mass cornea‚ v1i= velocity rod hitting eye‚ v2i= 0‚ v1f= o‚ v2f= velocity of flattening 2. m1iv1i + m2iv2i = m1Fv1f + m1fv2f (momentum in number 2) m1= mass

THE PHYSICS BEHIND CAR SAFETY FEATURES Cars contain several different types of safety features. These numerous safety features all have their own significance to the driver‚ as well as to the passengers. The purpose of this report is to show and express how physics is involved in automobile collisions and similarly how it is used to prevent injuries during accidents. Isaac Newton’s three laws of motion are used to describe the purpose of the three main safety features that cars are obliged to consist

* v2 = u2 + 2as * vav(Average Velocity) = (v+u)/2 Momentum‚ Force and Impulse Physics Formulas for momentum‚ impulse and force concerning a particle moving in 3 dimensions are as follows (Here force‚ momentum and velocity are vectors ): * Momentum is the product of mass and velocity of a body. Momentum is calculate using the formula: P = m (mass) x v (velocity) * Force can defined as something which causes a change in momentum of a body. Force is given by the celebrated newton’s law

Soccer Physics In this paper‚ I will explain the physics concepts of air pressure‚conservation of energy‚ gravity‚Inertia‚ and impulse momentum as they relate to the sport of soccer. I will also explain how knowing these laws can benefit how you play. The first physics concept I will talk about is air pressure. When you kick a soccer ball more energy transfers to a highly pressurized ball‚ as for a non inflated ball‚ the motion of the kick goes into the ball instead of moving the ball

Hypothesis: If a car is involved in a crash‚ a domino effect of reactions will occur. Background: The modern day automobile is a very complex piece of machinery that has a lot to do with the world of physics. Like every great invention‚ there was a beginning. For the automobile this beginning was in 1769. Nicolas Cugnot‚ a Frenchmen inventing for the French Army‚ came up with was first self-propelled‚ steam engined‚ three wheeled cart that was said to go as fast as walking speed. The next

there is an interaction between two objects‚ there is a force upon each of the objects. When the interaction ceases‚ the two objects no longer experience the force. Forces onlyexist as a result of an interaction. Velocity‚ Acceleration‚ Momentum‚ and Impulse Velocity‚ in physics‚ is a vector quantity (it has both magnitude and direction)‚ and is the time rate of change of position (of an object). However‚ quite often when you read ‘velocity’‚ what is meant is speed‚ the magnitude of the velocity
