Year 11 Preliminary Physics Assessment Tasks Year 11 Preliminary Physics Assessment Tasks Research Report – Models of the Universe Research Report – Models of the Universe Date Due: Friday 31st Agust Weighting: 15% Abstract The Universe is where everything exists‚ matter and energy. There are two main models of the universe: the geocentric model and the heliocentric model. The geocentric model is where the Sun and other planets‚ moons and stars revolve around the Earth. The

Kinetic theory of gases Question: How does odor travel from one place to another? Kinetic theory of gases A gas is composed of atoms or molecules The gas particles are in constant random motion Kinetic energy is transferred between particles as they collide Pressure The force exerted per unit of area Formula: pressure/force area Measured by barometer A vacuum is empty space‚ with no particles or pressure. Atmospheric pressure is the collision air particles with objects Units of

(a) If [B] is held constant while [A] is doubled‚ the reaction will proceed twice as fast. (b) If [A] is held constant while [B] is reduced to one quarter‚ the rate will be halved (c) If [A] and [B] are both doubled‚ the reaction will proceed 8 times as fast. 2.

I absolutely love jumping on the trampoline but I never really thought there was any physics involved. I knew you had to use a force to jump up and gravity pulls you back down obviously. An American inventor named George Nissen first invented the trampoline in 1935. (Silvia) A trampoline is defined as an elastic disc of hard canvas held up by metal springs attached to a metal skeletal frame. Kinetic and Potential energy allow you to be able to jump on a trampoline. PE=mgh this equation helps you

vertical velocity component is reversed in direction because of the reactive force of flat frictionless surface. The magnitude of VY is not changed. Since the collision between the particle and the surface is perfectly elastic there is no change in kinetic energy. This also been proven before by measuring the two variables before and after reflection. In order to change the speed of light‚ either the frequency or the wavelength has to change. The results have shown equivalent values for both of the

play and watch soccer games all of the time and yet few people actually realize the physics that are involved in almost everything that they see or do. While there are multiple ways that physics is used in a soccer game‚ this paper explores three parts and the physics that are involved in each one. The three parts that are going to be discussed are passing‚ heading‚ and throw-ins. These three can explain how physics can work from a soccer ball coming or going in each and every direction. Also‚ every
