on a spring is oscillating or vibrating if it is moving in a repeated path at regular time intervals. We call this type of motion harmonic motion. For an object to continue oscillating there must be a restoring force continually trying to restore it to its equilibrium position. For‚ the force exerted by an ideal spring obeys Hooke’s law. As an object in simple harmonic motion oscillates‚ its energy is repeatedly converted from potential energy to kinetic energy‚ and vice – versa. The content contained

just did it. I care about these laws because I’ve learned so much that I never really understood nor knew. Newton’s first law states “objects at rest will stay at rest unless an outside force acts on it and an object in motion will continue to stay in motion at constant speed in a straight line unless an outside force acts on it.” This means exactly what it says. If a ball is kicked it’ll go in a straight line until it hits a wall or someone stops it. If a ball is on the ground not moving it will stay

Today I will be talking about paper airplanes and what type of paper airplane flies the farthest also which one stays aloft the longest. Some of the topics I plan to discuss involve aerodynamics‚ drag‚ shape‚ size‚ forces‚ and gravity. Drag is the force of flight that pushes an airplane opposite to the direction it is moving. The biggest types of drag are friction‚ when air rubs against the surface‚ and difference in air pressure. Think of a drag like swimming treading through the water you can’t

Unit 2: The Ordered Universe Assignment 1. Why was the Ptolemaic system accepted as an explanation of celestial motion for over a thousand years? What did it explain? What system challenged the idea that Earth was the center of the universe? The Ptolemaic system says that the Earth is the center of the universe. Everything else surrounded the Earth. The Copernican system challenged the belief that Earth was the center of the universe. The major difference between the Ptolemaic and Copernican universes

BA-3-053‚ ext 7242 Email: Zolman@uniten.edu.my Course Description : The course begins by reviewing fundamental concepts and principles of statics‚ vectors and vector algebra. This basic knowledge gained will help to enhance the understanding of force analysis on particles in equilibrium and the principle of moment. This will eventually reinforced the studies on structural analysis with different loading conditions. The study on the characteristics of dry friction and belt friction will complete

Activity 1: X-Gliders Lesson Objective: Campers will learn about the forces of flight‚ weight and balance when they construct a glider. As they improve the design of their glider they will understand that a variable is a single change in the engineering. Set-Up: Each student will need two foam trays‚ a plastic knife and an x-glider template. Materials for weight and balance can be distributed at a communal table. Demo and discussion: Start off the lesson by asking your campers‚ “What are gliders

Four main forces act on an object in motion. They are thrust‚ drag‚ lift‚ and weight/ gravity. Weight is the force that pulls an object down‚ towards the center of the earth. Weight is equal to the mass of an object multiplied by the acceleration due to gravity. On earth gravity is 9.81 m/s² (W=MG) (Hopkins‚ 2012). Lift is the opposite force to weight. Thrust is the force that propels the object forward. For every action there is an equal but opposite reaction‚ therefore the force opposite

California at Irvine BURIDAN’S IMPETUS HYPOTHESIS Winner‚ 1998 Humanities Graduate Essay Award Abstract: I interpret the concept of impetus in the writings of the Paris Terminist‚ Jean Buridan (14th c.) as an accidental form that functions as a motive force according to Aristotle’s fundamental law of motion. I suggest how Buridan may have come to develop his particular hypothesis. I defend the traditional view that Buridan’s impetus is permanent‚ and in this respect a forerunner of Newtonian inertia‚

Accelerations) Abstract: The purpose of this experiment is to study the Newton’s second law and the behavior of objects for which all forces are not balanced. In this experiment‚ a small mass m will be connected to the dynamics cart by a string. The string will pass over a pulley at the table’s edge so that as the mass falls the cart will be accelerated over the table’s force. The cart will be released from rest and allowed to accelerate over a distance. Using a stopwatch‚ we determine how long it takes
