Dynamic Trolley Experiment
Lab Report
Experiment
Aim: To determine the acceleration of an object down an incline plane using various methods.
Research Question: Is there a relationship between the angle θ of the incline and the acceleration down the plane?
Equipment: * Ticker Timer (AC 50Hz ) * Incline (wood) * Meter ruler * Dynamic Trolley ( Mass: 380.55 ± 0.01g ) * Carbonated paper * Power Source (2W) * Data Logger * Motion Sensor * Tennis Ball
Method for ticker tape experiment: 1. We setup the equipment effectively as shown below in the diagram. 2. We then connected the ticker timer to the power source. 3. We had a person holding the car in place at the top of the incline/ramp. 4. At the same time another person passed carbonated paper through the ticker timer and stuck it on to the Dynamic trolley using tape. 5. Then the person that stuck the carbonated paper on to the dynamic trolley opened the power source and at the same time the person holding the Dynamic trolley in place let go of it and the trolley went down the inline ramp and was stopped by a person at the end of the ramp. 6. This same process was repeated 5 times for each of the 5 people participating in the experiment at 5 different angles (Angles are shown further down in the table). 7. Each carbonated paper was observed closely and the differences were clearly shown when the angles of decline changed.
Method for motion sensor experiment: 1. We setup the equipment effectively as shown below in the diagram. 2. A person operated the data logger (and therefore the motion sensor). 3. Another person held the tennis ball steady using a string attached to a part of the lab desk. 4. When the person that operated the data logger said that the motion sensor is ready to record the movement, then the person that held the tennis ball steady let go of the string. 5. Finally a person at the end of the decline ramp caught
