Newton's laws of motion

1. The pendulum of a clock swings back and forth. At what position will its kinetic energy be the greatest? At what position will its kinetic energy equal its potential energy? When the pendulum of a clock swings back and forth, the pendulum reaches its maximum potential energy at the top of the swing, and it reaches its maximum kinetic energy at the bottom of the swing. In the absence of frictional forces, the pendulum’s kinetic energy will be equal to its potential energy at the bottom of the…

the weight starts to drop the gravitational potential energy begins to decrease while the spring’s potential energy increases as it begins to stretch. During the middle the kinetic energy is at its maximum since the kinetic energy is the energy of motion. Lastly, as the weight nears the ground, the gravitational potential energy is at its minimum since the weight is as close as possible to the ground, the springs potential energy reaches its maximum since the spring is as stretched as it will go…

Grant Alexander Pd#6 11 November 2016 Trebuchet Engineering A trebuchet is a machine used in medieval siege warfare for hurling large stones or other missiles. How this machine works is not to complex but is also fascinating. The object that is being shot is held in the sling, which is on a launch trough whose job is to make sure the shot is straight. Also the trough is there to prevent the sling getting caught in the framework of the trebuchet. When putting the arm of the trebuchet down,…

scientists and mathematicians as a parabola, and objects that fly in the shape of a parabola are said to be in parabolic motion. A projectiles motion can be broken up into two separate pieces, horizontal and vertical motion. These two motions act independently of each other meaning no matter how much one of them changes the other will be unaffected. While in parabolic motion the only motion…

The purpose of the experiment was to determine how altering the amount of mass in a makeshift rocket will affect its distance. Our hypothesis stated that when more mass is added to the rocket, its distance will also increase. To investigate this theory, we conducted an experiment in which the mass of the rocket would be changed using differentiating amounts of water. To measure the height of the bottle rocket, we took rope and attached it to the girth of the liter bottle to determine how high…

The foot and ground exert an equal and opposite force on each other. This is known as the ground reaction force.12 The position and acceleration of the runner's center of mass regulates the direction and magnitude of the ground reaction force. For instance, a runner sprinting from a standstill. Throughout the initial phase of acceleration, the body is inclined forward and therefore the center of gravity falls in front of the contact surface. After many gait cycles, the runner reaches top speed…

Motion Down an Inclined Plane Andrew Park Ms. Jatindranauth SPH 3U7-A September 28, 2017  Introduction The purpose of this lab is to determine the effect displacement has on the final velocity of a trolley on an inclined ramp. What is hypothesized is that as the distance the trolley rolls down decreases, the velocity should decrease with it. Also, because the trolley should uniformly accelerate, the standard equations of motion can be used to calculate many different variables (one such being…

more quickly than the other side. Inclination of rail tracks will balance the wear on both sides, increasing the time between replacements of the rail and reducing the risk of failure to corner at a bend. Mechanism: Application of Uniform Circular Motion: Tilting In Train High competition from other means of transportation have driven railway companies for increased performance, which means shorter time for travelling and improving the ride comfort. Railways for high speed trains are railways…

The goals of this project are: To define the piecewise function formulas defining the coaster To create a replicated graph of the formulas To determine the maximum height of the coaster as well as the longest drop, in comparison to other great coasters in the world To determine how long the passengers will be in the air, how fast the coaster is going when hitting the “splashy zone”, and where the “splashy zone” should be built To determine the maximum height a passenger can reach during…

INTRODUCTION Can the magnitude of gravity be found by measuring the period in relation to the length of the string of an oscillating pendulum? The aim with this lab was for us to gain a greater understanding in the area of oscillations and simple harmonic motion. Also to determine if the use of a pendulum is a good strategy for measuring the gravity. I found this experiment to be very interesting since I’ve seen and used pendulums a lot before, but I have never really reflected on why they…
