ROTATIONAL MOTION CENTRE OF MASS AND ROTATIONAL MOTION INTRODUCTION- For describing the motion of rigid bodies‚ we shall introduce the key concept of ‘centre of mass’. This concept enables us to understand how we can apply justifiably the Newton’s laws of motion‚ in essentially the same form to objects of large size including even the astronomical objects like the planets and the stars. KINDS OF MOTION OF A RIGID BODY- A rigid body may have three kinds of motion- (1) Pure Translation Motion- in such

Projectile Motion You have probably watched a ball roll off a table and strike the floor. What determines where it will land? Could you predict where it will land? In this experiment‚ you will roll a ball down a ramp and determine the ball’s velocity with a pair of Photogates. You will use this information and your knowledge of physics to predict where the ball will land when it hits the floor.

AP Physics HW #1 Multiple Choice 1. A car travels 30 miles at an average speed of 60 miles per hour and then 30 miles at an average speed of 30 miles per hour. The average speed the car over the 60 miles is (A) 35 m.p.h. (B) 40 m.p.h. (C) 45 m.p.h. (D) 10 m.p.h. (E) 53 m.p.h. Answer: B. Method: Vavg = Δx/Δt The average speed is the total distance traveled‚ divided by the total time. They give us all distances traveled is‚ so we just need to find the time. We find the time‚ by applying

Good morning/ afternoon everyone First of all‚ thank you for inviting me to this exhibition of Poetry in Motion. I was inspired to create my work based on the poem called This Man‚ by the Solomon Islands poet‚ Celo Kulagoe. This poem is a critique of the all-encompassing power of money‚ which can dictate to presidents and prime ministers alike and can ruin those with few resources. This resonates with the current issue of Coal Seam Gas mining and its wealthy supporters‚ while the dangers to the

market. Otherwise‚ they could fail to sustain their existence. For the success and next stages of development in this market‚ creation and innovation became most important factors. One of major smart phone competitors‚ RIM (Research in Motion LTD.)‚ known as BlackBerry especially emphasizes importance of innovation as we can see the name of company. For the last decades‚ most of electronics companies had focused on mass production‚ thus they paid attention to develop specialized machines

Motion in a Viscous Medium Aim The aim of this experiment is to measure the terminal velocity of spherical beads falling under gravity in a liquid determine‚ and hence determine its viscosity using Stoke’s law. Introduction When a stationary solid object is complete or partially immersed in a fluid‚ it experiences an upthrust or buoyant force. According to Archimedes’ principle‚ this buoyant force B is given by where ρ is the density of the fluid‚ Vs is the immersed volume of the
