Found inside – Page 9Ans. Uniform. The distance travelled by B in equal interval of time of 15 minutes is unequal, i.e., motion of object B is non-uniform as it travels unequal ... Found inside – Page 10When a body travels unequal distances in equal intervals of time or moves with unequal speeds, it is said to possess non-uniform motion. Hence an external force is needed to move a body uniformly in a circle. This post includes: a=(v-u)/t = (16.66-11.11)/5 = 5.55/5 = 1.11 m/s2. Motion Uniform and Non-Uniform Motion: Uniform Motion: When an object covers equal distance in equal interval of time, the motion is called uniform motion. For such a body there will be an acceleration. The direction of motion at any instant of time is along the tangent to the circular path at that instant. KSEEB Science Solutions For Class 9 Question 14. Motion Uniform and Non-Uniform Motion: Uniform Motion: When an object covers equal distance in equal interval of time, the motion is called uniform motion.

Uniform circular motion is another example of 2-dimensional motion, where the object moves with uniform . State of Motion: An object is said to be in the state of motion if it changes its position with respect to time and its surroundings. A person moves from point O in a straight line to a point X 50m, and return from X to point Y in direction XO 20m. Velocity: It is the speed of a body in given direction. : a car running with uniform speed of 1 0 k m / h r on a straight road. (i) Distance is a scalar quantity which requires only magnitude but no direction. One small square in x-axis represents, t = ⅖ sec. The tip of second’s hand: minute’s hand and hour’s hand of a watch displays uniform circular motion on the dial of the watch. For example - if a moving vehicle covers a distance of 10 km every hour, the motion of the vehicle is called uniform motion. The minute hand of a wall is 10 cm long. This means that the object does not cover the equal distance in equal time intervals. As the object covers equal distances in equal intervals of time, it is said to be in uniform motion. In uniform circular motion, only the speed of the body is constant.
