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

Newton ’s laws of motion Newton ’s laws of motion are three physical laws that form the basis for classical mechanics. They describe the relationship between the forces acting on a body and its motion due to those forces. They have been expressed in several different ways over nearly three centuries and can be summarized as follows: 1. First law: The velocity of a body (a state of rest or of uniform motion in a straight line) remains constant unless the body is compelled to change that state

and field event similar to the long jump. The only difference between the two is that the hop‚ skip‚ and jump involve a hop and a step‚ whereas the long jump involves just a jump. In the first phase of the triple jump‚ the competitor builds momentum by sprinting down the runway‚ planting their lead foot at the marked board‚ and “hops” into the air‚ cycling one leg around into phase two. After completing the cycle‚ the lead foot strikes the ground again initiating the “skip”‚ where the opposite
