Science Term 1 – Rubber Band Racer – Liam Gist A rubber band racer consists of a corflute base‚ a rear axle with rubber wheels and a front axle with plastic wheels. It is powered by a rubber band that can be wound around the rear axle and when released it propels the racer forwards. When the rubber band is wound around the axle it has elastic potential energy and when this energy is release it is transformed into kinetic energy that rotates the rear axle and wheels propelling the car forwards. As

Daniel Bernoulli (Groningen‚ 8 February 1700 – Basel‚ 8 March 1782) was aDutch-Swiss mathematician and was one of the many prominent mathematicians in theBernoulli family. He is particularly remembered for his applications of mathematics to mechanics‚ especially fluid mechanics‚ and for his pioneering work in probability andstatistics. Bernoulli’s work is still studied at length by many schools of science throughout the world. In Physics :- He is the earliest writer who attempted to formulate a kinetic

Weatherspoon‚ Chloe Parry‚ Miya Reyes‚ Juan Mousetrap Car Project Report Purpose: The purpose of this project is to build a mouse trap car and apply it to Newton’s laws of motion. Newton’s first law states that every material object continues in its state of rest or in uniform motion in a straight line unless it is compelled to change that state by forces acting on it. Newton’s second law states that the acceleration of an object is directly proportional to the net force acting on the object

Time Machine The English department just got a time machine! This will be so much fun. I fear that I might get lost back in time. I’m excited for all the things I’ll learn from this exciting trip. I’ve seen many movies involving time machines that dont end up very well such as‚ people getting lost or eaten by dinosaur. Im going to see Sir Issac Newton and I’m very excited. Im going to vissit him because‚ I want to learn about physics and all the things he discovered. Life was very

Force‚ Motion‚ Newton’s Laws‚ Momentum‚ and Impulse What is force? Force is a push or pull upon an object resulting from the object’s interaction with another object. There are two types of force‚ contact forces‚ and forces resulting from action-at-a-distance. A contact force can be frictional forces‚ normal forces‚ applied forces‚ and air resistant forces. The formula for contact force is F = ma. This type of force occurs when two objects are contacting each other physically. If you kick a ball

Material science is an all-inclusive science that we can apply to regular occasions. Boxing is a donning occasion that applies the numerous laws of material science. Why might anybody be keen on taking in the material science of boxing? These laws of material science can give one contender an edge over their adversary or can be their most exceedingly awful foe. We may watch a bout and not so much recognize what to make of the developments. Subsequent to finding out about the material science included

The Hurdle Before a diver jumps off of a springboard‚ he does a sort of hop-skip step called a hurdle. After doing a few steps‚ the diver leaps up into the air with his arms raised. When he lands back down on the tip of the board‚ he swings his arms down past his legs and then up‚ leaping into the air and off of the board. The purpose of this hurdle is as follows: A diver cannot simply stand on the end of board‚ step off‚ and expect to have the power to go up or the momentum to rotate his
