Science > Physics > Newton’s Laws of Motion > Reference Frames Before studying Newton’s laws of motion, we shall understand a very important concept of reference frames in this article. Motion is a Relative Concept: Motion is always with respect to the observer. Consider a person A is standing in a train moving in the […]
Science > Physics > Circular Motion > Numerical Problems on Centripetal Force – 02 Example – 19: The vertical section of a road over a bridge in the direction of its length is in the form of an arc of a circle of radius 19.5 m. Find the greatest velocity at which a car can […]
Science > Physics > Circular Motion > Numerical Problems on Centripetal Force – 01 Example – 01: A 0.5 kg mass is rotated in a horizontal circle of radius 20 cm. Calculate the centripetal force acting on it, if its angular speed of revolution is 0.8 rad /s. Given: Mass of a body = m = […]
Science > Physics > Circular Motion > Centripetal and Centrifugal Force In this article, we shall study the concept of centripetal force and centrifugal force, their expressions, and examples. Centripetal Force: A force which acts on a body performing circular motion and acts along the radius of the circular path and directed towards the centre of […]
Science > Physics > Circular Motion > Centripetal Acceleration In this article, we shall study the concept of centripetal acceleration and expression for it. Centripetal acceleration is also called radial acceleration. Accelerated Motion: Velocity is a vector quantity which has magnitude as well as direction. Either magnitude or direction or both change the motion is […]
