Loop one end of the elastic cord around a rod attached to the trolley. Keep the force constant by making sure that the cord is always stretched by the same amount as the trolley moves. Practice doing this. 3.Choose and cut through a dot near to the start of the tape. Do this

The same person measured and recorded the height and length of the incline plane and level horizontal track to ensure consistency in the recording of data. By having the same person read all of the measurements minimized the degree of uncertainty in position and angle of reading values. 3. The same person recorded all measuring values on the ticker tape to ensure consistency in the recording

Aim of the experiment: To investigate how the period of a simple pendulum varies with its length. Variables: Manipulated: The length of the pendulum‚ l Responding: The period of the pendulum‚ T Constant: The mass of the pendulum bob‚ gravitational acceleration Apparatus/Materials: Pendulum bob‚ length

the accelerating object? Purpose: The purpose of the practical is to find how mass affects acceleration and how it affects also the force of the accelerating body. To do this we are going to do the ticker tape experiment where an accelerating body pulls a tape through a consistent 50 dot per second ticker timer. The acceleration body in this experiment will be a small trolley pulled by a string that is pulled by the downfall of different masses which will then tell how mass affects acceleration. Hypothesis:

using a ticker tape timer Aim: To determine a value for the acceleration due to gravity‚ g. Equipment: n ticker tape timer n ticker tape n pulley mass n string n adhesive tape n 30 cm rule n scissors n glue n Introduction As an object falls freely it will accelerate towards the centre of the Earth. This is due to the gravitational attraction between object and the Earth. The magnitude of this acceleration can be determined by analysing the motion of the falling mass with a ticker tape timer

Theory: Gravitational acceleration is constant on Earth g=9.8m/s2 Therefore‚ when the golf ball is dropped‚ the acceleration will be equal to gravitational acceleration agb=9.8m/s2 Given there is no air resistance‚ this means that when the golf ball is dropped from a given distance‚ according to the formulas‚ the golf ball will accelerate
