support partly because the density of the moon is the same as that of the rocks just below the crust‚ or upper mantle‚ of the earth. A major difficulty with this theory is that the angular momentum of the earth‚ in order to achieve rotational instability‚ would have to have been much greater than the angular momentum of the present earth-moon system.<br><br><b>Formation in Orbit Near the Earth</b><br>This theory proposes that the earth and moon‚ and all other bodies of the solar system‚ condensed independently

is accelerating‚ decelerating and in the event of an abrupt stop. When in uniform motion‚ one cannot feel the effects of the cars inertia as separate to oneself‚ but the separate inertia is shown when the car is stopped suddenly. In a high speed collision‚ each car comes to a stop rapidly. Occupants not wearing their seatbelt will continue at the original speed of the car (as per the Law of Inertia) until acted upon by a force. An unrestrained occupant will then move at a high speed until:Colliding

(a) Find its x and y components of momentum. (b) Find the magnitude and direction of its momentum. 2. A 0.100-kg ball is thrown straight up into the air with an initial speed of 15.0 m/s. Find the momentum of the ball (a) at its maximum height and (b) halfway up to its maximum height. 3. How fast can you set the Earth

did not make perfect sense for me to note. As far as I am concerned the khan academy does not lecture it so I am not too sure in what to do about this. I am assuming finding velocity is the sole purpose of applying the law of conservation of momentum. Is this true? I also would like to note that a graph could not be drawn in some situations again due to me lacking the technology to send photos of handwritten notes. Hence there is sadly no examples of a problem for translational equilibrium

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 of; seatbelts‚ airbags‚ headrests‚ those of

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

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.

The crumple zone is a structural feature in which can be mostly found in automobiles. They are constructed to absorb the kinetic energy from impact during an accident by controlled deformation. In order to absorb the impact of a head on collision‚ most of the time crumple zones are designed to be in the front part of a vehicle‚ they can also be found on the rear and sides of vehicles. Isaac Newton’s first law states that an object in motion will stay in motion with the same speed and direction unless

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

involved in automobile collisions and how physics can and has been used to prevent injuries in collisions. The aspects that are primarily being dealt with are things such as seatbelts‚ airbags‚ headrests and all. SEAT BELT The job of the seatbelt is to hold the passenger in place so the passenger is almost part of the car which prevents the passenger from flying forward as the car stops abruptly in the case of a collision. When a car stops suddenly due to a collision with another object such
