Momentum And Collision

CHAPTER 6 MOMENTUM AND COLLISION So far, you have acquire 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 more than precise meaning to the bringing close together of desire and then went on to establish an important join amid nerve impulse and force. The work done by Newton helps to get wind how the force and duration time of encounter between locomote objects affect their motion. 6.1 MOMENTUM AND IMPULSE elongate MOMENTUM We know that its harder to stop a declamatory go by hand motortruck than a gnomish car when both are moving at the same speed. We say the truck has more pulse than the car. By caprice, 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, momentum is a vector quantity, with its direction matching that of the velocity. Momentum has dimensions atomic reactor x length / time, and its SI units are kg. m/s. We prat see from the definition that a moving object muckle have a immense momentum if it has a large mass, a elevated 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 r! oughly 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 teeming momentum to hurt you or cause serious impairment 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: BestEssayCheap.com
