1.1 GRAVITY AND GRAVITATIONAL FIELDS 1.1.1 Define weight as the force on an object due to a gravitational field. Weight is the force experienced by an object due to the presence of a gravitational field. This force is directly related to the strength of the gravitational field acting on an object and the mass of that object. m = mass‚ g = acceleration due to gravity m = mass‚ g = acceleration due to gravity Fg = mg Fg = mg 1.1.2 Explain that a change in gravitational

Projectiles Practical Report 1. Introduction Velocity is a vector measurement of the rate and direction of motion or‚ in other terms‚ the rate and direction of the change in the position of an object. [1] Velocity can be found many ways through various suvat Equations and their rearranged forms. For example v2=u2+2as in which the square of the final velocity can be found if you know the objects initial velocity‚ the acceleration and the distance travelled. Using such formulae makes it possible

Physics can be related to sports and fitness on many different levels. When you lift weights‚ play sports or even buy athletic equipment you probably don’t know how much physics was really put into any of it. Weightlifter’s need to know which workout is better. Also the equipment athletes use relate to physics. Manufactures design equipment for athletes‚ which involve physics. The manufactures need to think about what will make the object better and what materials will cause the equipment

Physics of Sports A sport isn’t just about winning; it is also about strategy‚ how the game is played‚ and performance of the athletes. Physics is the last topic many people associate with sports. However‚ physics can be applied to every aspect of any sport‚ which is a study referred to as Sports Science. Components of this study include gravity‚ projectile motion‚ acceleration‚ force‚ vectors‚ etc. With new technology that physics in sports introduce‚ more possibilities of physical science can

Beverly Hearst IB SL Physics Rate of Vaporization Design Lab Research Question: How does changing the surface area of a sample of water affect the time taken for the water to boil? Background: By changing the containers of the water‚ the surface area of the water is thus being modified as the same volume of water is spread out over smaller or larger surfaces. The measure being compared is the time each sample of water will take before it reaches the boiling point‚ 100 C°. The relationship

An inclined plane is a flat supporting surface tilted at an angle‚ with one end higher than the other‚ used as an aid for raising or lowering a load. Inclined planes are widely used to move heavy loads over vertical obstacles; examples vary from a ramp used to load goods into a truck‚ to a person walking up a pedestrian ramp‚ to an automobile or railroad train climbing a grade. Inclined planes are widely used in the form of loading ramps to load and unload goods on trucks‚ ships‚ and planes. Wheelchair

Sam Preusser Mr. Staude U.S. History 25 April 2013 Truman Doctrine VS. Marshall Plan The years after the war brought times of disagreement and argument. The United States worked at this time to contain and control the spread of communism. During the years of WWII and the Cold War this idea was prominent and an issue America thought must be solved. Their were two strong attempts to fight communism. These attempts were the Truman Doctrine and the Marshall Plan. These ideas go hand in hand making
