Toy cars have been played with by children for many years. Would one wonder the way a model or toy car rolls down a hill? One would think it would be because it has wheels‚ this is true but there is more to a car rolling downhill than it having wheels. Gravity is the force that is keeping all things on the ground. The heavier an object is the more gravity has an effect on its momentum. If you put a toy car on a downhill slope it will begin to roll because of gravity. The more the car weighs will

Physics Lab report Aammar Paracha Section MX Feb 6th 2015 OPTICS Abstract: This experiment revolves around using light rays and lenses. The experiment also discusses different properties of light rays. This experiment uses different lenses and measurements to produce images and observes different techniques to obtain the image position. Question and Answers: 1. Use your data to verify the Law of Reflection and then use Snell’s Law to calculate

Title Experiment with a spiral spring (Oscillation) Objective 1. To show how the time of vertical oscillation depends on the load 2. To determine the spring constant 3. To determine the effective mass of the spring Introduction In this experiment‚ it is to show how the time of vertical oscillation depends on the load‚ to determine the spring constant and to determine the effective mass of the spring. An ideal spring is remarkable in the sense that

Professor Oersted Hans Christian Oersted’s Experiment * Hans Christian Oersted performed an important experiment which showed that there was a connection between electricity and magnetism. * When a current was switched on through a wire‚ it made a compass needle turn so that it was at right angles to the wire. * The current had produced a magnetic field strong enough to cause the compass needle to turn. Additional effects due to experiment * It was already known that an electric

Sunlight and Concave Mirror for Cooking Researchers: Pamatmat‚ Mikaela Franchesca Siacon‚ Maria Sherlene Dianne Cruz‚ Jeremy Anne Lardizabal‚ Zaree Dominique Macagba‚ Danielle Martinez‚ Kyrene Teacher: Sir Vincent Sabong Abstract The researchers thought of trying to come up with a makeshift solar cooker in order to test if this way of cooking may be effective and useful in substituting for a frying pan and a stove. The solar cooker may be a possible alternative when cooking outdoors under
