Centripetal Force Requirement
Uniform circular motion could be elaborates as the motion of an object within a circle at a constant speed. As an object moves within a circle and it is constantly changing its direction. Since of this direction modification, you can be certain in which an object undergoing circular motion is accelerating (even if it is moving at constant speed). And in accord along with Newton's laws of motion, an accelerating object must be acted upon through an unbalanced force. This unbalanced force is in the similar direction as the direction of the acceleration. For objects in uniform circular motion, the net force and following acceleration is concentrating inwards. Circular motion needs a net inward or "centripetal" force.
a car of mass 800kg is pulling a trailer 300kg where sin a=1|200.Resistance to motion(apart from gravity) is 1.5N per kg of mad for each vehicle.calculate the pulls of the engine a
The v-t graph of a car is shown in the accompanying figure. What is the displacement of the car from t = 0.00 s to t = 15.0 s?
Joule's laws (J.P. Joule) Joule's first law The heat Q generated while a current I pass through a resistance R for a particular time t is given by following Q = I2 R
Hence refractive index µ can be determine by measuring the diameter of Newton's rings first with air and then with the liquid for same value of m.
