Space Definitions Field Vector A field vector is a single vector that describes the strengths and direction of a uniform vector field. For a gravitational field‚ the field vector is g Weight Weight is defined as the force on a mass due to the gravitational field of a large celestial body such as the Earth Gravitational Potential Energy Gravitational Potential Energy is the energy of a mass due to its position within a gravitational field. On a large scale GPE is defined as the work done

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

Question 1(10 marks) Comment the following statements (a) The volume coefficient of thermal expansion of water is negative for temperatures in the range 0 to 4 °C. (b) The triple point of water‚ 0.01 °C‚ and 611.73 Pa‚ is one of the primary fixed points on the Kelvin absolute temperature scale. (c) The volume coefficient for the thermal expansion of a solid is twice the linear coefficient for thermal expansion. (d) A temperature of 26.85 °C is the same as 300 K. (e) The surface temperature

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

ballet dancers you think of grace and beauty. While you watch a dancer dance you never think of the physics and mathematics behind their every move. Physics is described as a thing that is all about measurement‚ and that if you know the units of measurement that physics uses and how they work you will understand everything else you’ll learn about (Dennis and Moring 1). The textbook definition of physics is “the study of matter and energy and their relationships” (Zitzewitz 1). Ballet cannot be defined
