WebSep 4, 2024 · Centre of mass of a system is the point that behaves as whole mass of the system is concentrated on it and all external forces are acting on it. For rigid bodies, … Webτ = r x F = rF sinθ n. It is a vector quantity. If the nature of the force is to rotate the object clockwise, then torque is called negative and if rotate the object anticlockwise, then it is called positive. Its SI unit is ‘newton-metre’ and its dimension is [ML 2 T -2 ]. In rotational motion, torque, τ = Iα.

WebNewton’s second law of motion is strictly applicable to point masses only. To apply the Newton's law of motion to rigid bodies, the concept of centre of mass is introduced. The … WebThe table edge method (Figure 4) can be used to find the center of mass of small rigid objects with at least one flat side. The object is pushed slowly without rotating along the surface of a table towards an edge.

WebThe radius of gyration or gyradius of a body is always about an axis of rotation. It is characterized as the spiral distance to a point which would have a moment of inertia. The radius of gyration is a geometric property of a rigid body. For example, the centre of mass. It is equivalent to the body’s real dissemination of mass. WebJun 16, 2024 · Systems of Particles and Rotational Motion Class 11 Notes Physics Chapter 7. • A rigid body is a body with a perfectly definite and unchanging shape. The distances between all pairs of particles of such a body do not change. • Centre of Mass.
