Bali Aim: The aim of this experiment was to determine the spring constant “k” of a spring using Hooke’s Law and Simple Harmonic Motion. Theory: Part 1: We know from the theory that the Time Period “T” for any spring that undergoes simple harmonic motion: T = 2π * √ (m/k) Where “T” is the Time Period of the spring; “m” is the mass attached to the spring and “k” is the spring constant of the spring used. After mathematically manipulating the equation to make k the subject of the equation

Palmeri claim that superordinate level advantage is only present at short stimulus presentation times. They suggest that at short presentation times‚ categorization relies more on contextual cues provided by the background‚ rather than actual object information. We aim to find if the superordinate level advantage at short presentation times can be attributed to contextual cues. We compared human reaction times when categorizing bird pictures as containing either an animal (superordinate level)‚ or bird

this is because there will be more downward pull from gravity‚ as the terminal velocity for a paper helicopter is low. Variables: Independent variable will be the mass that we change throughout the experiment. The dependant variable will be the time that we measure for the helicopter to reach the floor. Finally the controlled variables include‚ the helicopter itself. As well as the height from which the helicopter is released. Apparatus: Paper‚ Scotch tape‚ Scissors‚ Ruler Method: Create

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

As mentioned‚ our results suggest that the distraction times vary greatly on different individual factors. However‚ with the overall averages at 237 for no distractions compared to 315 for distractions‚ our team’s hypothesis still holds true that distractions greatly affect reaction time. Our experiment demonstrated to us that there are two factors intertwined in influencing reaction time: the distraction itself and the individual’s ability to react while distracted. For example‚ a cellphone app
