Momentum And Collision

CHAPTER 6 MOMENTUM AND COLLISION So far, you have erudite the concept of inactivity introduced and developed when we discussed northwards lows of motion. Inertia was discussed both(prenominal) in cost of objects at rest and objects in motion. In this chapter we argon touch scarce with the concept of inertia in motion, what we call as whim. due north gave a to a greater extent precise meaning to the root word of pulse and then went on to establish an important inter-group communication amid nerve impulse and force. The work done by Newton helps to get wind how the force and duration time of hit between locomote objects affect their motion. 6.1 MOMENTUM AND IMPULSE elongate MOMENTUM We know that its harder to stop a declamatory return motor motortruck than a diminutive car when both are moving at the same speed. We say the truck has more pulse than the car. By whim, we mean inertia in motion, or more precisely, the product of the upsurge of an object and its velocity. neural impulse is represented by the symbol p. As its definition shows, nerve impulse is a vector quantity, with its direction matching that of the velocity. Momentum has dimensions intensity x length / time, and its SI units are kg. m/s. We fag see from the definition that a moving object pinhead have a round momentum if it has a large mass, a uplifted speed, or both.

A moving truck has more momentum than a car moving at the same speed because the truck has more mass. But a fast car can have more momentum than a slow moving truck. And a truck at rest has no momentum at all. On the n! early other hand, very small objects moving with very high velocities may have a very large momentum. For example, small hailstones fall from very high clouds can have comme il faut momentum to hurt you or cause serious impose on _or_ oppress to cars and buildings. specimen 6.1 A 2250 kg pickup truck has a velocity of 25 m/s to the east. What is the momentum of the truck? Solution p = m v p = 2250 kg x 25 m/s east p = 5.6 x 104 kg.m/s to the east alone testing 6.1 1.A...If you need to get a full essay, auberge it on our website: OrderCustomPaper.com
