Explain Circular and Orbital Motion
Let's start by looking at circular motion with constant speed. Can there be acceleration in this problem? Yes, velocity includes speed and direction and acceleration can mean speeding up, slowing down, or moving at constant speed but changing directions. During circular motion, the object in circular motion is constantly changing the direction of its motion.
Consider a yo-yo that you are swinging in a circle parallel to the ground, above your head. What keeps the yo-yo changing direction? The string does. If the string breaks, the yo-yo will no longer move in a circle. The tension in the string supplies the force to accelerate the yo-yo into circular motion.If the length of the string is r (in meters), the speed is v (in m/s), the time to complete one revolution, one time around your head, is called the period, T(in seconds).v = 2pr / T in the tangential directionand ac = V2 / r inward in radial directionthis is called the centripetal acceleration (in m/s2) and is supplied by a centripetal force (in newtons) ofFc = mv2/r inward in radial directionsupplied by the string where m is the mass (in kg) of the yo-yo.
What is Potential Gradient Magnitude of electric field at a point on an equipotential surface equal's rate of alter of potential, ΔV, with distance Δx, as point moves perpendic
VELOCITY- TIME GRAPH: The graphs which represents the variation of velocity of an object with respect to time is known as velocity- time graph.
Q. What do you mean by lateral shift? and What could be the angle of incidence to have maximum lateral shift? Q. For what angle, lateral shift is minimum?
When a semiconductor is doped with a P-type impurity, each impurity atom will (A) Acquire negative charge. (B) Acquire positive charge. (C) Remain
Centrifugal pseudoforce A pseudoforce which occurs while one is moving in consistent circular motion. One feels a "force" directed outward from the center of motion.
