(a) mass of an apple [1] (b) number of joules of energy in 1 kilowatt-hour [1] (c) wavelength of red light in a vacuum [1] (d) pressure due to a depth of 10 m of water [1] J02/P2/Q2 2. A student uses a micrometer screw gauge to measure the diameter of a wire. He fails to notice that‚ with the gauge fully closed‚ the reading is not zero. (a) State and explain

Lebanese American University Classical Physics 3 . Projectile Motion Objectives: Students will measure the maximum height H and the range R of a projectile motion. They will study the effect of the shooting angle on H and R. Material used: 4 rulers‚ track‚ metallic ball‚ landing track‚ A4 white paper‚ red carbon paper‚ timer + supply‚ gun + protractor. Theory: A projectile is an object upon which the only force acting is gravity. There are a variety of examples of projectiles: an object

Simple Harmonic Motion Lab Report In this lab‚ I will study the principles of simple harmonic motion using an oscillating pendulum. If I were to design an experiment that would help me study the properties of an oscillating pendulum and investigate what causes a pendulum to swing faster or slower‚ I would prepare several masses (e.g. 20g‚ 50g‚ 100g‚ 200g‚ etc.) that can be attached to a string‚ several strings of varying lengths from 0.1m to 1.0m that are strong enough to support the weight of the

Bruce Silver Professor Shawn Dry History 1520 14 June 2010 Why Should We Explore Jupiter’s Moon Europa? The planet Jupiter‚ some 500 million miles from Earth is a very unique planet. Besides being 1200-1500 (estimates vary) times larger than the Earth‚ The planet Jupiter is surrounded by a small solar system by itself. The planet Jupiter has some 72 moons orbiting it at present count‚ and these moons come in all shapes‚ sizes‚ and physical variations. Many of these moons have quite interesting

Name: Kaili Smith Pendulum 1. Research to find equations that would help you find g using a pendulum. Design an experiment and test your design using Moon and Jupiter. Write your procedure in a paragraph that another student could use to verify your results. Show your data‚ graphs‚ and calculations that support your strategy. The time it takes a pendulum to complete one back-and-forth swing‚ called the pendulum’s period‚ depends only on the pendulum’s length and

POLYNOMIALS IN DAILY LIFE Polynomials are a combination of several terms that can be added‚ subtracted or multiplied but not divided. While polynomials are in sophisticated applications‚ they also have many uses in everyday life. Although many of us don’t realize it‚ people in all sorts of professions use polynomials every day. The most obvious of these are mathematicians‚ but they can also be used in fields ranging from construction to meteorology. Polynomials in Construction and Material

Pendulum is an object that‚ due to action of gravitational force‚ swings back and forth at a regular rate around a fixed point if it is pulled aside and let go. A simple pendulum consists of a weight hanging at the end of a string or wire. The path travelled by the weight is called the arc of the pendulum. The period of oscillation is the time it takes the weight to pass back and forth once over this arc. The length of the pendulum is the distance between the point at which the pendulum is fixed

examples of work done=force x distance What is work? Work in physics is the transfer of energy; work is done on an object when an applied force moves it through a distance. The link between work and energy is work done equals energy transferred. The units for the two are also the same (joules). E.g. 500J of work = 500J of kinetic energy. Work is calculated with the formula: work done=force x distance moved For example‚ if a force of 10 newton (F = 10 N) acts along point that travels 2 meters

If there isn’t any artificial gravity present then the human body is extremely stunned which forces all the biological functions to break down. Astronauts that are in orbit for a long period of time tend to show major decreases in their bone strength‚ muscular tone‚ and also
