Step 1: The hand holding the the weight in the pendulum will release the weight and allow it to swing forward to hit the car. This is potential energy by the force of motion of the weight on the pendulum. Potential energy is the energy an object produces due to its position. The pendulum swinging is it being in motion therefore it has kinetic energy. The force shown form this could be Applied Force. Applied force is a force that is applied to an object by a person or another object. Step 2: After

LIGHT DEPENDENT RESISTANCE INTRODUCTION In the society‚ some times street lights glow in day time due to any reason. In mines area people face many difficulties due to absence of light in the nights. In frontier and hilly areas‚ people face many problems due to damaged street lights. For solve above these problems‚ we create a device in which the lights glow in night and in day time‚ they off automatically and don’t glow. Due to use of it‚ we can solve above problems and can also save electricity

BOOM’ S PROBLEM PS 4.3 – Torque (Rotational Equilibrium) Problems 1. A crane supports a 3.0 kN weight as shown. The crane’s boom is 8.0 m long and is at an angle of 30˚ from the horizontal. If the hydraulic support is attached to the boom 2.0 m from the bottom of the boom‚ then: a) what is the compressional force in the hydraulic? b) what is the magnitude and direction of the force on the pin at the bottom of the boom? a) ∑Torque = 0 F cos 30˚ x 2.0 = 3000 cos 30˚ x 8.0 F = 24

Next would be how you hold the guitar while sitting or standing. This is a very simple technique and very hard to do incorrectly. The back of the guitar will be flush against your midsection. If the guitar covers most of your torso‚ then it may be too big. If it is too big‚ it will be difficult to play smoothly. Now that you know how to hold the guitar‚ and where to put your hands‚ you should know how to put the strap on the guitar‚ simply referred to as “strapping the guitar”. Both ends of the strap

2-8 Refraction and polarization of light 5. Experiment Results A. Linearity of light 1. The light beam does go straight when we tested on the angle board. 2. As the source of light beam was getting farther away from the slit‚ the beam becomes narrower and shorter in addition to fading. This is because light particles escape more when they travel to go through the slit. B. Law of reflection Angle of incidence is the angle formed by a ray incident on a surface

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

the Condition Myopia is a common vision impairment in which close objects are seen clear but far objects appear blurry. Nearsightedness occurs if the eyeball is too long or the cornea‚ the clear front cover of the eye‚ has too much curvature. As a result‚ the light entering the eye isn’t focused correctly. This inaccuracy is called a refractive error. In other words‚ an over focused fuzzy image is sent to the brain. Figure 1.1 – Myopic Eye uncorrected With a Myopic eyeball‚ the point of clarity
