Center of Gravity The point in a body or system of bodies at which the whole mass may be considered as concentrated. When an object’s weight is distributed uniformly‚ the center of gravity lies at its geometrical center. For irregular shaped objects‚ the center of gravity is near to the concentration of its mass. Equation: Where: X= center of gravity xi= distance of the objects from fulcrum or arbitrary axis mi= mass of the object Sample Problems 1.) Suppose your lab partner has

1)Scoliosis posture: the centre of gravity has shifted to either the left or the right depending on which side has the main curve on the spine. This will typically give the appearance of a wonky sideways walk. 2)Military posture: most people believe it is a perfect posture‚ but it is not ideal for these reasons. The centre of gravity has shifted slightly pushing the pelvis anteriorly and up‚ drawing the shoulders back‚ which draws the scapula back medially pushing the chest out and up‚ this causes

Torques equilibrium‚ and center of gravity Introduction Torque is a quantitative measure of the tendency of a force to cause or change the rotational motion of a rigid body. A torque is the result of force acting at a distance from an axis of rotation. An essential thing to keep in mind is that the magnitude of the torque is equal to the product of the forces perpendicular distance and magnitude. Theory The magnitude of the torque (t) is found from the product of the force F and

earth; gravity. Whenever I think of gravity‚ the same questions never fail to come to mind. What exactly is gravity? Could human life possible go on without gravity? How exactly does gravity work in terms of numbers and formulas? How was gravity truly discovered and defined‚ and by whom? Gravity is universal‚ and it not affects earth and its inhabitants‚ but also the entire nebulous of stars and planets. Gravity is the force that pulls all things toward the center of the earth. Gravity holds your

Firstly the “Compass and Torch” is a story about a young boy setting out on a camping trip with his father. The compass and torch are used symbolically throughout the narrative to reflect the boy’s feelings and relationship to his family. The compass in the story could symbolise a lack of direction or the absence of a relationship between the father and his son. This can be demonstrated when they are about to leave the car for their journey together at the bottom of the hill. “The man looks up –

Gravity is the force that keeps objects close to the earth Not only does gravity keep objects close to the earth it also keeps the solar system revolving the sun Gravity was discovered by Isaac Newton Acceleration of objects that is due to gravity on Earth is 9.8 m/s Also‚ according to Mr. Newton’s First Law‚ once the egg was moving‚ it didn’t want to stop. The container of water interrupted the egg’s fall‚ providing a safe place for the egg to stop moving so you could recover it unbroken

Compass: - They don’t have the compass - Can’t find a way to work their relationships out Torch: - The torch could signify that they can ’see’ how they want their relationship to be but because they do not have the compass they can’t get there. Other Notes: “With bleached end-of-summer grass‚ bruised here and there with heather and age-old spills of purple granite” Very descriptive but the boy doesn’t take notice of it.

Compass And Torch The worst thing you can do is to forget your child‚ not physically forget it in the supermarket‚ but mentally forget it. The worst thing is to forget to take time of with your child‚ listen to it and talk to it. Show them that you are there for them and only for them. Some people never learn how to talk to children‚ even though it is their own children‚ but it dose not mean that you cannot listen to them and pay attention. Sometimes it is just as important as talking. In this short
