    various safety precautions taken. Because when an object stops‚ or is stopped by a collision‚ the same change in momentum occurs no matter the size of the force or the time interval‚ these sheets of metal are critical to the passengers safety. The metal sheets not only absorb energy from the oncoming vehicle‚ but they also slow it down; and because the change in momentum is equal to the impulse‚ the longer it takes for a force to reach the passenger‚ the smaller the force will be. Another safety feature

    Momentum and Simple 1D Collisions PhET Lab Introduction: When objects move‚ they have momentum. Momentum‚ p‚ is simply the product of an object’s mass (kg) and its velocity (m/s). The unit for momentum‚ p‚ is kgm/s. During a collision‚ an object’s momentum can be transferred to impulse‚ which is the product of force (N) and time (s) over which the force acts. This allows us to write the momentum-impulse theorem: Procedure: Play with the Sims  Physics Motion  Collision Lab Work with 1D collisions

    Romar M. Cabinta EXERCISES 15 WORK‚ ENERGY‚ AND POWER A. CONCEPTUAL QUESTIONS 1. Is work done when you move a book from the top of the desk to the floor? Why? Yes. It is because the displacement of the book from the top of the desk to the floor and the force that is applied to the book is parallel with one another. 2. State the law of Conservation of Mechanical Energy in two ways? The law of conservation of energy states that energy may neither be created nor destroyed.

    energy than mass. Still objects have no kinetic energy. Hint: Energy variables are capital Momentum proportional to mass and velocity p=mv Units= kg time m/s And is vector in as direction as velocity Conservation laws are applied in closed systems only Collisions are closed Momentum is conserved///// total energy is conserved Momentum always conserved in collisions thus collision problems are aways momentum problems Total energy is always conserved Types of collisions: Elastic collisions Kinetic energy

    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 momentumimpulse 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
