Finger Response Times to Visual‚ Auditory and Tactile Modality Stimuli By Christopher Watts 9MLO Introduction: The time it takes from when an individual responds to a certain stimulus that they have detected is commonly referred to as reaction time. This delay in time is caused by the amount of time it takes information to go through the nervous system and then towards your brain. Your brain acts as the processor of your body and translates these informative signals so that your body can act

Focus on Application: Week Two Student’s Name MAT/205 Due Date Instructor’s Name For the example of a ball being thrown up into the sky and then landing on the ground‚ we can model a quadratic equation to show the path of the projectile at various points in time (projectile motion). That is to say‚ each point plotted on the graph (parabola) will be a measurement to this effect: Suppose a ball is thrown into the sky at a velocity of 64ft/sec from an initial height of 100ft. We would set the

1. Define gravity An attracting force that acts between any 2 objects. 2. What is the difference between mass and weight? Weight is the measure of the gravitational attraction of an object‚ while mass is the amount of matter in an object‚ the measure of an object’s resistance to motion. 3. How does mass affect the motion of an object? The greater the mass‚ the harder it is to speed up or slow down an object. 4. What finding(s) did Galileo uncover regarding falling objects? He conducted an experiment

Mousetrap Car Report What sources of friction (both good and bad) does one need to consider in designing an effective mouse trap car? Try to come up with at least four [4] Explain how Newton’s first‚ second and third laws apply to the performance of your car [3] First Law: An object in motion will stay in motion‚ and object at rest will stay at rest unless acted upon by an outside force. In other words‚ the mouse trap car will not move unless an outside force will cause it to move

The purpose of the egg crash is to design‚ build‚ test‚ and evaluate a landing pad to protect an egg from the collision of a hard surface falling from various heights. An individual should be able to describe the collision in terms of changing momentum‚ impulse‚ impact force‚ and impact time. All moving objects have a quantity of motion‚ otherwise known as momentum. Momentum of a moving object can be found by multiplying the mass of the object by the velocity. Because mass is measured in kilograms

Isaac Newton discovered how gravity worked and had evidence. He showed that it was real at the leaning tower of pisa. That was proof and you still insist he goes to jail. There is much more proof than this. He has shown the example and proved it‚ so why is he in jail? He is in jail because you want him to be. He showed the idea of how gravity worked. I will start with how he got his idea and how it worked. Isaac Newton discovered the basic idea of gravity and proved how it worked when he saw

Stress is the human body’s way of reacting to any form of a threat. When your body feels threatened‚ the nervous system responds to this by releasing stress hormones which prepare the body for any sort of emergency situation. Your heart rate increases‚ muscles begin to tighten‚ blood pressure heightens‚ breath quickens‚ and senses sharpen. These physical changes increase your strength and stamina‚ speed your reaction time‚ and enhance your focus. When at an ideal level‚ stress helps you to stay focused

In the seventeenth century‚ the Scientific Revolution gave birth to discoveries of new mathematics and sciences. Isaac Newton‚ in particular‚ was one of the many physicist or mathematicians. Born in new England to a prosperous farmer‚ Isaac Newton would later develop principles to develop modern physics with his most famous work‚ Mathematical Principles of Natural Philosophy. Isaac Newton was the son his parents gave birth to. His father soon died three months after his birth‚ thus leaving him with

STEP 1 – SWING FUNDAMENTALS BALL FLIGHT LAWS The five physical laws of ball flight are invariable‚ no matter who swings the club or where or how a club contacts the ball: • Clubhead speed - The speed a club is travelling when it makes solid contact with ball determines how far the ball will go. • Clubhead path - A ball’s starting direction is determined in part by the line along which the clubhead swings as it contacts the ball. • Clubhead face - The direction of a ball is determined in part by
