Calculating the Force Needed to Move an Object Up a Slope

forces : In physics, when frictional forces are acting on a sloped surface such as a ramp, the angle of the ramp tilts the normal force at an angle. When you work out the frictional forces, you need to take this fact into account. Normal force, N, is the force that pushes up against an object, perpendicular to the surface the object is resting on. The normal force isn’t necessarily equal to the force due to gravity; it’s the force perpendicular to the surface an object is sliding on. In other words, the normal force is the force pushing the two surfaces together, and the stronger the normal force, the stronger the force due to friction.     What if you have to push a heavy object up a ramp? Say, for example, you have to…

How to Calculate the Force of Gravity on the Earth ?

Gravity : Starting with the physics equation for the force of gravity, you can plug in the mass and radius of the Earth to calculate the force of gravity near the surface of the Earth. The equation for the force of gravity is F = (Gm1m2) /r^2 and it holds true no matter how far apart two masses are. The gravitational force between a mass and the Earth is the object’s weight. Mass is considered a measure of an object’s inertia, and its weight is the force exerted on the object in a gravitational field. On the surface of the Earth, the two forces are related by the acceleration due to gravity: Fg = mg. Kilograms and slugs are units of mass; newtons and pounds are units of weight. You can use Newton’s law of gravitation…

windmill working Principle

What is a Windmill? Up until recently, people still only had visual impressions of what a windmill is, often associating it with the past and particularly before the industrial revolution. Today, things have come full circle, if you will and there is now a growing demand for large, technologically advanced windmills across the world. The term wind energy or wind power describe the process through which wind turbines convert the kinetic energy in the wind into electrical energy by the use of generator. What this introductory guide seeks to do is describe the apparatus in layman’s terms and also outline how they work and what they were intended for originally and the purposes for which they are used today. We begin with a brief definition of what a windmill is. It was originally a structure with…
