The conversion of potential energy to kinetic energy is what drives the roller coaster‚ and all of the kinetic energy you need for the ride is there once the coaster goes down the very first hill. Once the coaster gets going‚ there are different types of wheels that help keep the ride smooth. Roller coasters don’t have engines. But they do have energy. Once all passengers are in the coaster‚ the carts get released and begin to roll down the first hill. The force of gravity makes them accelerate downwards

coasters often start as a chain and motor exercises a force on the car to lift it up to the top of a very tall hill. At this height‚ GPE is at its highest‚ as we can see through the formula: GPE = mass x gravitational field strength x height (for all physics in relation to Earth‚ take g to be 10 m/s2 or 10 N/kg) We can see through this formula that as the height increases‚ so does the GPE‚ which will then be converted into KE‚ or kinetic energy. This is the energy that takes place as the “car” is falling

Physics in My Daily Life “Write an essay of 1500 words‚ double spaced‚ in standard fonts ‚ giving credible references on the use of physics in your daily activity. You need to mention 5 or more activities where physics is used. Please follow the APA format.” As a senior in college‚ I lead a rather busy life. My days usually follow the same routine and pattern. I wake up at 7am everyday‚ so I am rather tired. To get going in the morning‚ I usually drink a cup of coffee. Then I attend my classes

to who is the rightful inventor of this object‚ most sources claim that Newton’s Cradle was invented by Marius Morin and was later coined “Newton’s Cradle” by English actor in 1967. This popular executive toy exhibits various concepts related to physics including friction‚ collisions‚ conservation of energy‚ and conservation of momentum. Momentum is force of moving objects. It can be measured by multiplying an object’s mass and velocity. Basically‚ the concept of conservation of momentum is that

.Physics is the field of scince that controls the Earth‚ the Moon‚ the Sun and the Universe It is the science of matter and its motion‚ space-time and energy. Physics describes many forms of energy - such as kinetic energy‚ electrical energy‚ and mass; and the way energy can change from one form to another. Everything surrounding to us is made of matter and Physics explains matter as combinations of fundamental particles which are interacting through fundamental forces. It will not be an exaggeration

Momentum‚ p‚ is the product of an object’s mass (kg) and its velocity (m/s). The unit for momentum‚ p‚ is kg·m/s. During a collision objects transfer momentum to each other‚ resulting in different motions than before the collision. In this activity you will study
