Learn how to make inferences, hypotheses, and experiment designs related to kinetic energy with Physics concepts. Identify, relate, and analyze variables for maximum marks in SPM.
E N D
BENGKEL PENINGKATAN PELAJAR “PHYSICS” SPM 2012 • JPNKL • Penceramah: Thong Kum Soon A rolling ball gain kinetic energy, but without frictional force, it won’t change direction.
Part B Question no 3 and 4 • Based on the diagrams given, • (a) make one suitable inference . • (b) state one appropriate hypothesis that could be investigated. • (c describe how you would design an experiment to test your hypothesis • In your explanation, state clearly the following : • aim of the experiment • variables in the experiment • list of apparatus and materials • arrangement of the apparatus • the procedures of the experiment, which includes the method of controlling the manipulated variable and the method of measuring the responding variable • the way you would tabulate the data • the way you would analyse the data • [12 marks]
IDentify • Identify the MV and RV from the diagram and questions. CIRCLE IT UP • Identify the apparatus given to link to the PHYSICS CONCEPT of experiment. • Relate the experiment which you had done before in school and identity the relationship between the variables.
Identity the variable from the text and diagram. • (a) Manipulated variable • (b) Responding variable • (c) Fixed variable (can be measured) • ---NOT TYPE OF SUBSTANCE • Underline the variables of MV and RV from the diagram. Use the variables to substitute the format of Planning Experiment.
Procedure • 1. State the initial measurement of MV. • 2. State the ways of measurement of RV with apparatus and follow with formula (if necessary) • 3. Repeat the experiment with 4 different MV values. a1,a2,a3 and a4. • .
Part B Paper 3 • Format • Boyle’s Law • Force motion • Buoyant force (Force and volume) • Pressure (Pressure and height and density) • Heat ( mass and temperature) • Charles Law (Gas Law) • Light (lense formula)
