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

Kinematics: Real life video analysis using Logger Pro 3 Name: ___________________________ Class: 15S_________ Date: ______________ _________________________________________________________________________ In this exercise‚ we will be using the software “Logger Pro” to investigate the motion of an object in the following scenarios. 1. An object sliding down an inclined slope. 2. A ball projected at an angle (projectile motion). 3. A cupcake paper holder dropped vertically (air resistance). There

The world that we live in is constantly producing new ideas and methods to benefit the lives of many. It is a fascinating opportunity to reflect on all the inventions that have been made throughout each of our lifetimes. Two very important individuals that shaped the world we live in today are Sir Isaac Newton and Georges-Pierre Seurat. These two figures have impacted the science and art world. While some similarities between the processes of Newton and Seurat are evident‚ the differences are salient

“Law of Interaction” Law of Interaction “For every action‚ there is an equal and opposite reaction” The statement means that in every interaction‚ there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. Interaction between the hammer and nail A hammer exerts a force on the nail and drives it into a board . But this is not the only force present for there must also be a force exerted on

Johanna Malmstrom Mr. Manolio Honors Physics 17 January 2014 Egg Impact Crash Test My project was constructed by using simple materials that could be found around the house and were transformed into a protective device for two Grade A Large Eggs. The materials of my project are cardboard‚ tape and a hot glue gun. I used a cardboard box whose flaps folded in over top‚ but taped open the flaps so that the height would meet the 20 cm minimum requirement. I made sure the width was less than 50 cm

What is momentum? Momentum of a body is defined as the mass multiplied by the velocity of this object. Momentum= m x v Momentum and Newton’s second law of motion: The resultant force is proportional to the change in momentum per a second. We know that force = mass x acceleration. So F (mv-mu)/t F m (v-u)/t = ma so F=kma Momentum is a vector quantity: Momentum has a direction as well as a magnitude Momentum and Newton’s first law of motion: An object remains at

Background Information: Equation One: T=2πlg Where T = the period of the pendulum (s). This is the time taken for the pendulum to return to its starting position. l = length of the pendulum g = the rate of acceleration due to gravity (ms-2) * In
