acceleration due to gravity using the pendulum motion or computer assisted technology and identify reasons for possible variations in the value 9.8m.s-1 AIM: To measure the value of acceleration due to gravity on the surface of the earth. APARATUS: A weight attached to a thick‚ non-elastic string that was tied to a clamp on a retort stand. METHOD: 1) Set the pendulum in motion‚ making sure it doesn’t swing in a deflection greater than 30° (as greater than 30° will cause the string to lose tension)

Physics Moment of a force: Moment of a force = force x perpendicular distance of the line if action if the force from fulcrum Law of moments: When a body is in equilibrium the sum of the clockwise moments about any point equals the sum of the anticlockwise moments about the same point. Centre of mass: Centre of mass is the point where whole mass of the body assumes to be concentrated. II. If the vertical line through the centre of mass is outside the base it will be a topples but if it’s passed
