PPT-Gravitational Field Strength

To help explain how two bodies that are not in contact can exert a force on one another ie gravitational magnetic or electrostatic we use the concept of fields Fields are spheres of influence They are invisible and intangible they simply demonstrate how strong a characteristic is at a certain distance. https://. www.youtube.com/watch?v=6a0-Ry-fufA. Newton discovered that gravity attracts any two objects depending on their . masses. and their . distance. .. Fg. is proportional to the two masses:. Fg. MRI USER GROUP. Alison PINFOLD. Sat 31. st. .

Any two objects will exert an attractive force on one another based on the following: . Electric fields are created by . electric charges. . Any object with a charge has an electric field around it. Opposite charges attract each other; like charges repel. An electric field is a region in which a charge experiences a force. . D.S. . Hajdukovic. GBAR Collaboration Meeting. 18. th. April 2012.

Gravitational Potential Energy & Kinetic Energy  GPE When you lift an object up, energy is transferred from your muscles in to gravitational potential energy of the object. Gravitational potential energy (GPE) is energy stored in an object because of its position in the earths gravitational field. P3 Challenge – A rotating fan completes 1200 revolutions every minute. Consider the tip of a blade, at a radius of 0.15 m. a) Through what distance does the tip move in one revolution? What are b) the tip’s speed and c) the magnitude of its centripetal acceleration? . Due to inhomogeneous magnetic field from local bar magnet. Causes T2 shortening. Field strength dependent. Major factor with deoxyhemoglobin (acute hematoma) and hemosiderin (chronic hematoma).
