blurry. Farsightedness occurs if your eyeball is too short or the cornea has too little curvature‚ so light entering your eye is not focused correctly. Figure 2.1 – Hyperopic Eye uncorrected With a Hyperopic eyeball‚ the point of clarity falls behind the retina rather than on it. This makes far objects clear and far objects clear. Figure 2.2- Hyperopic Eye corrected by convex lens When a Hyperopic Eye is correct by a convex lens‚ the light rays are refocussed on the retina. This now makes

MOMENTUM QUESTIONS 1. Which has greater momentum: a train at rest or a moving skateboard? Since the train is not moving‚ it has zero momentum. The skateboard‚ as long as it has some speed‚ will have more momentum‚ since p = m*v. 2. What are the ways to increase impulse? Impulse depends on the magnitude of the applied external force and the time that the force acts on the system. By increasing either of those‚ impulse on a system will be increased‚ and the system’s momentum will change accordingly

This resistance is called drag. Drag is the result of a number of physical phenonmena. Pressure drag is that which you feel when running on a windy day. The pressure of the wind in front of you is greater than the pressure of the wake behind you. Skin friction‚ or viscous drag‚ is that which swimmers may experience. The flow of water along a swimmer’s body creates a frictional force that slows the swimmer down. A rough surface will induce more frictional drag than a smooth surface. To

factors can play into an accident. Road condition‚ mechanical failure‚ driver error‚ or simply an ’act of God’? Despite the countless reasons for a car accident‚ one factor is always present‚ no matter what the case: physics. Every accident that has ever occurred has involved physics. Using references found in the class text‚ in science journals‚ and on the Internet‚ I will prove this to you. Take‚ for example‚ two cars traveling in opposite directions at 100km/h. One of the drivers dozes off and

Measurement of the distance‚ the thickness and the radius of curvature Purpose : To learn how to use vernier caliper‚ micrometer and spherometer to measure internal and external diameters of a pipe‚the thickness of a copper rods‚ and the radius of curvature of spherical lenses. 1) Vernier caliper: As shown in Fig. 1 the main fixed scale in the vernier caliper has 1 mm gradations while th sliding scale (vernier scale) has 0.05 mm gradations. The smallest division of vernier scale is called
