1 Mass and Inertia MV: Mass of plasticine RV: Period of Oscillation CV: Length of jigsaw blade 1. Plasticine with a mass of 30 g is attached at the end of jigsaw blade. 2. The jigsaw blade is displaced horizontally to one side and then released so that it oscillates. The time taken for 10 oscillations, t is recorded by a stopwatch./ The period of oscillation is recorded. 3. The steps are repeated 4 times by using plasticine balls with mass = 40.0 g, 50.0 g, 60.0 g and 70.0 g. 2 Force and acceleration MV: Force RV: Acceleration CV: mass 1. Switch on power supply and a ticker timer. 2. The trolley is pulled with a rubber band to a fixed extension and released so that the trolley accelerates down the runway. 3. The ticker tape obtained is cut into strips of 10‐ ticks and the acceleration is calculated by using the formula, a=v‐u/t 4. The steps are repeated with 2, 3, 4 and 5 identical elastic cords. 3 Height and velocity MV: Height RV: Velocity CV: Mass of trolley 1. Set the track so that the height of track, h = 15.0 cm. 2. Switch on the power supply and allow the trolley to come down the track. Calculate the velocity, v (of the trolley) from the ticker‐tape. 3. The steps are repeated for h = 20.0cm, 25.0cm, 30.0cm and 35.0cm. a.c. power supply

6 Volume of water displaced and buoyant force MV: Volume of water displaced RV: Buoyant force CV: Density of liquid 1. By using a spring balance, the weight of a cylinder metal rod in air is measured and recorded as Wo. 2. The rod is then lowered into the water until the volume immersed, V is 50 cm3. 3. The reading on the spring balance, W is recorded. The buoyant force is calculated using formula Buoyant force = Wo ‐ W. 4. The steps are repeated for volume of the rod immersed, V = 100cm3, 150cm3, 200cm3 and 250cm3. 7 Temperature and Pressure MV: Temperature RV: Pressure CV: Volume 1. The water bath is heated and continuously stirred until the temperature of the water reaches 20°C. 2. The pressure of the air is measured by using the Bourdon gauge. 3. The experiment is repeated by increases the temperature 40°C,60°C, 80°C and 100°C.4

1 Depth and wavelength of water wave MV: Depth RV: Wavelength CV: Frequency water 1. Fill in the ripple tank with water at depth 2cm. *2. A piece of perspex plate at thickness 0.3cm is placed at the middle of the ripple tank. 3. Switch on the power supply, vibrating motor and lamp. 4. Freeze the water wave by using the stroboscope. 5. Measure the distance between two consecutive bright OR dark fringes on white paper using a ruler.// The wavelength is recorded. 6. Repeat the experiment by using a perspex plate at thickness 0.6cm, 0.9 cm, 1.2cm and 1.5cm. * The depth of water also can be adjusted by changing the volume of water. 2 Wavelength and frequency of water waves MV: Frequency of wave RV: Wavelength CV: Depth // velocity 1. Fill in the ripple tank with water at depth 2cm. 2. Switch on the power supply and adjust the frequency of vibrating motor for f1. 4. Freeze the water wave by using the stroboscope. 5. Measure the distance between two consecutive bright OR dark fringes on white paper using a ruler.// The wavelength is recorded. 6. Repeat the experiment by adjusting the frequency of vibrating motor for f2, f3, f4 and f5.
