kinetic energy

Consider a body of mass 'm' which is initially at rest. When a force 'F' is applied on the body, let it start moving with a velocity 'V' and cover a distance 's'. The force produces acceleration 'a' in the body. The force 'F' does work when it moves the body through a distance 's' and this work don..

Andrew, who weighs 37 kgs, is running in a football field. If he has acquired 74 joules of kinetic energy, then what is the velocity with which he is running? Kinetic energy is modeled by the equation E = × m × v 2 , where E is the kinetic..

Energy is a number that we associate with a system of one or more objects. If a force acts on one of the objects, making it move, then the number changes. After countless experiments, scientists and engineers realised that if the scheme by which we assign these energy numbers i..

The table shows the data of a moving object with velocity ( v ) and kinetic energy (E). Choose the model and its equation whcih best fits the data? Velocity( v ) 0 4 8 12 16 20 Kinetic Energy(E) 0 96 384 864 1536 2400 => Quadratic; E = 10 v 2 or Quadratic; E ..

Kinetic Theory of Matter - This theory explains the physical properties of matter in terms of motion of its molecules. According to this theory, every substance (solid, liquid or gas) consists of a large number of minute particles called molecules . A molecule may be defined as the smalle..

Kinetic Theory of Gases - The word 'Kinetic' means due to motion. The Kinetic Theory of Gases is based on the idea that gases consist of atoms and molecules moving ceaselessly and randomly with all possible velocities in all directions. Each of these gas particles has ..

We know that a hotter body has greater internal energy than a similar colder body. Thus, higher temperature means higher internal energy and lower temperature means lower internal energy. According to the kinetic theory of gases, the internal energy..

All gases are made up of large number of minute particles called molecules. Large distances separate the molecules so that the actual volume of the molecules is negligible as compared to the total volume of the gas. The molecules are in a state of constant rapid motion in all directions, co..

We know that a hotter body has greater internal energy than a similar colder body. Thus, higher temperature means higher internal energy and lower temperature means lower internal energy..

At normal temperature, fuels are stable even in the presence of air. This is because, the activation energy of combustion reaction is high. When a mixture of fuel and air is burned, a flame has to be applied, that is the mixture has to be ignited. Near the flame, the contents are ra..
