TOPIC OF EXPERIMENT
VARIABLES MV: Mass of plasticine RV: Period of Oscillation CV: Length of jigsaw blade
PROCEDURES 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.
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. 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.

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.
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.
