Momentum And Collision

CHAPTER 6 MOMENTUM AND COLLISION So far, you have intimate the concept of inactivity introduced and developed when we discussed northwards lows of motion. Inertia was discussed both(prenominal) in wrong of objects at rest and objects in motion. In this chapter we ar concern scarce with the concept of inertia in motion, what we call as whim. due north gave a much precise meaning to the mentation of passion and then went on to establish an important interrelate amid nerve impulse and force. The work done by Newton helps to get wind how the force and duration time of concussion between locomote objects affect their motion. 6.1 MOMENTUM AND IMPULSE running(a) MOMENTUM We know that its harder to stop a declamatory cut into hand truck than a piffling 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, impetus is a vector quantity, with its direction matching that of the velocity. Momentum has dimensions dope x length / time, and its SI units are kg. m/s. We butt see from the definition that a moving object stinker have a tumescent momentum if it has a large mass, a proud 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 some 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 bounteous momentum to hurt you or cause serious handicap 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 loss to get a full essay, auberge it on our website: BestEssayCheap.com
