translating‚ rotating‚ and vibrating in a container. If the molecules are moving around quickly then they have a large sum of kinetic energy which means that they are warm appear warm. But if energy is removed from the molecules start moving slower and if all energy is removed from the molecules then the system that the molecules exist in will have zero energy. When matter has zero kinetic energy means that the matter has a temperature of absolute zero‚ or zero kelvin. It is impossible for anything to be

Vitamin D is essential for all individuals in order to absorb calcium and phosphorus from the intestines. the four main subtypes of rickets are Nutritional‚ Vitamin D Resistant‚ Vitamin D Dependant‚ and Congenita. the most common one is Nutritional rickets‚ which is caused by a dietary deficiency of vitamin D‚ calcium‚ phosphorus‚ or all three. Vitamin D Resistant Rickets‚ is a genetic condition caused by a defect in the kidneys. Children with this

shape‚ the more potential energy it has. For example‚ a person on a ladder has more potential energy than a person on the ground because they have done more work to get up there. Kinetic Energy Kinetic Energy is the energy of motion. The more work an object has done‚ the more kinetic energy it has. the amount of kinetic energy an object has can be calculated by the formula: KE = 1/2 MV2 It can be defined as the works needed to accelerate an object of a certain mass from rest to its stated velocity

greater distance meaning the potential energy increases. You experience this phenomenon all the time; think about riding your bike or pulling your sled to the top of a big hill. The potential energy you build going up the hill can be released as kinetic energy (the movement energy that takes you down the hill). On our trip to Thorpe Park we experienced the thrills of the rides and were given a talk explaining the science behind them. This will hopefully explain more about the science behind the

the work done to a system is equal to the system’s change in energy. Here‚ the object starts with kinetic energy [KE = (mv^2)/2] and friction brings it to rest by doing an equivalent amount of work. Work is‚ in this case‚ the product of the force of friction and the distance the object slides while coming to rest. Therefore‚ the distance the object slides is directly proportional to the kinetic energy of the object‚ and inversely proportional to the force of friction‚ i.e. d = (mv^2)/(2F).

The formula for determining kinetic energy is KE = mv2‚ where KE is kinetic energy‚ m is mass of the projectile‚ and v is velocity. Based on this formula‚ the velocity of a projectile has traditionally been considered far more important than its mass in
