Answer: Acceleration of a body is defined as the rate of change of its velocity with time. Distance covered by this taxi from time t1 = 4h at P to time t2 = 8 h at S, is given by distance = 50 (t2 - t1), Hence distance = PQ SP = Area of rectangle PSRQ, Case (ii) : When speed (velocity) as well as acceleration is non-uniform (variable). t - The time interval. Distance travelled, s= area of trapezium OABC. 3) You may also go through this comprehensive class 11 physics notes on Gravitation topics. Important Questions Math's pdf, MCQ smartech('identify', ''); When the body is moving along a straight line with uniform acceleration, a relation can be established between velocity of the body, acceleration of the body and the distance travelled by the body in a specific time by a set of equations. Notes for class 11 Physics, Chemistry papers class 8 science, Important In time t covering a distance s as shown in the graph 8.1 (a). Let us derive the relation of force F = ma from Newton's second law: According to the Newton's 2 nd Law of motion, the rate of change of linear momentum of a body is directly proportional to the applied external force and in the direction of force. .
