Unscramble the following and match the column A with column B. Column A Column B 1 . Simple pendulum (a) OETMREDO 2 . Swing (b) IEPROIDCIOMTNO 3 . Displacement (c) CILSOALTNIO 4 . Measuring distance (d) PEDMSEEOTER 5 . Measuring speed (e) ETOVCR

The unscrambled column B is given below: Column A Column B 1. Simple pendulum (a) OETMREDO = ODOMETER 2. Swing (b) IEPROIDCIOMTNO = PERIODIC MOTION 3. Displacement (c) CILSOALTNIO = OSCILLATION 4. Measuring distance (d) PEDMSEEOTER = SPEEDOMETER 5. Measuring speed (e) ETOVCR = VECTOR 1. Simple pendulum (b) PERIODIC MOTION In simple pendulum, when a bob moves to and fro, it oscillates about mean position. This motion is called oscillatory or periodic motion. The pendulum repeats its path in equal interval of time. 2. Swing (c) OSCILLATION The swing oscillates around its mean position, moving forward and backward. The motion of a swing is a kind of periodic motion. 3. Displacement (e) VECTOR Displacement can be only defined by using both magnitude and direction. Therefore, it is a vector quantity. 4. Measuring distance (a) ODOMETER Odometer is an instrument which measures the total distance travelled by a body. It is placed in a vehicle along with the speedometer. 5. Measuring speed (d) SPEEDOMETER Speedometer is an instrument which measures the speed at which a body is moving at that instant of time. It measures the speed of the object in kilometer per hour. After matching column A with column B: Column A Column B 1. Simple pendulum (b) PERIODIC MOTION 2. Swing (c) OSCILLATION 3. Displacement (e) VECTOR 4. Measuring distance (a) ODOMETER 5. Measuring speed (d) SPEEDOMETER
