Circular motion‚ gravitational field‚ and oscillation 1.Define gravitational field strength: Force per unit mass 2. Explain why there is a point between two point masses at which the gravitational field strength is zero. Because gravitational fields of two masses are in opposite directions‚ so there is a point where it is zero What is meant by angular velocity The rate of change of the angular displacement of an object as it moves along curved path. Generally when asked to test

Physics can simply be defined as the science that studies the mechanics of matter‚ motion‚ energy‚ and force. Dance in my opinion is a type of performance categorized as a form of art that involves the mind‚ body‚ soul‚ and a little something called physics. Dancing is a personal favorite hobby of mine‚ but I’ve never really considered the physics side of dancing which seems odd considering all the different movements and techniques that involve many principles of physics such as rotational inertia

For Lab 1‚ my partner and I will be demonstrating the law in which connects the period of the pendulum‚ expressed as T‚ to the length of the string‚ expressed a L. The system the lab will be based on will include a pendulum with a weight of W suspended at a fixed point by the string with a variable length of L and an angle theta to be measured using a protractor. The variable T will be measured as the period of time needed for the weight of the pendulum to swing back and forth once. For part 1 of

BUOYANCY PHYSICS Student: Instructor: Criteria : Design Introduction The purpose of this experiment to find the effect of temperature on buoyancy . Backround Information Buoyancy (also known as the buoyant force) is the force exerted on an object that is wholly or partly immersed in a fluid. The symbol for the magnitude of buoyancy is B or FB As a vector it must be stated with both magnitude and direction. Buoyancy acts upward for the kind of situations encountered in everyday experience

Energy Energy can neither be created or destroyed‚ only changed into different forms. Energy is only useful when it can be converted into different forms. Energy is often dissipated - spread out and lost. 9 types of energy: Thermal (heat) - flows from hot to cold objects Kinetic (movement) - anything that is moving has this Light - from the sun‚ light bulbs et cetera Elastically potential - when things are stretched Gravitational potential - anything that can fall Electrical - whenever

Pendulum Raiyan Hassan SPH3U September 20‚ 2011 Introduction A pendulum is a device which consists of a mass attached to a string from a frictionless pivot which allows it to swing back and forth. In this experiment‚ the time it takes for a pendulum to go through a period is going to be measured. The time it takes for a pendulum to go through one period can depend on factors such as the length of the string‚ mass‚ or the degree in which the pendulum is released from (amplitude). In this

to have a healthy‚ good‚ and natural sex life. Dr. Stephen Holt‚ a pioneer of Integrative Medicine and author of several books‚ including The Anti-Aging Triad (2017)‚ Sleep Naturally (2003)‚ presents his scientific take on both man and woman’s sex life. In Holt On: Sex the Natural Way‚ Dr. Holt acknowledges that “Making love is a very important and underestimated part of a healthy lifestyle.” Admitting that he is no “sexpert‚” Dr. Holt‚ nevertheless‚ presents provocative ideas on the current repression

Chapter 13 – States of Matter Pressure (P) – the amount of force per unit area. Pressure=F/a or P=F/a Pascal’s Principle “Any change in pressure at a point on a confined fluid is transmitted throughout the fluid”. Any change is transmitted throughout the fluid. Buoyancy & Archimedes Principle “When an object is submerged in a fluid‚ it displaces a certain volume of that fluid. The amount of force pushing upward on the object is equal to the density of the fluid (Ï) times the acceleration
