Tags: Question 12 . $\begingroup$ @user248881 In the standard model of particle physics all photons are point particles, i,e, have no size. It is given as K E = a s 2, where a is a constant. kinetic energy synonyms, kinetic energy pronunciation, kinetic energy translation, English dictionary definition of kinetic energy. The kinetic energy of a moving object can be calculated using the equation: Kinetic energy = $$\frac{1}{2}$$ x mass x (speed) 2. 2 See answers Nonportrit Nonportrit The amount of kinetic energy an object has depends on its "speed." Only mass. You are very important to us. Linear Kinetic energy of a object is dependent upon the linear speed of an object and its mass( we can use the scalar term “speed” as energy is a scalar quantity and is independent of the direction of motion of body). Kinetic energy depends on A. only mass. When the particles are moving very fast, we feel the substance and say "That's hot!". The equation for kinetic energy is *KE = ½mv**2*, so the greater the mass and the greater the velocity, the greater the kinetic energy. are solved by group of students and teacher of Class 11, which is also the largest student community of Class 11. The E=hν. Kinetic energy is energy a object has while its in motion so the key word is speed. Thus kinetic energy of the emitted photoelectrons depends on wavelength, frequency of the incident photon and work function of the metal but does not depend on the intensity. Relevance. Mass is weight because of how much weight a object has would decrease the speed. A. The Questions and Answers of The kinetic energy 'K' of a particle moving in a straight line depends up on the distance 's' as K=as square, force acting on the particle is ??? While kinetic energy is not an invariant in classical mechanics, the gain or loss in kinetic energy due to internal forces within a system is an invariant. The Planck constant transforms energy to a number that miraculously is the frequency of the light that will be built up by zillion such photons. This is because the temperature of a substance depends on the kinetic energy of the particles. Examples of Kinetic Energy: 1. Active 4 years, 10 months ago. Potential energy, stored energy that depends upon the relative position of various parts of a system. 2 $\begingroup$ Closed. D. Mass and velocity. It is the energy stored in a moving body. The unit for energy is joules. Definition of potential energy, gravitational potential energy, elastic potential energy and other forms of potential energy. The force acting on the particle is [closed] Ask Question Asked 4 years, 10 months ago. B. height. Kinetic energy is the energy of motion. Unlike forces, energy is a scalar, so direction doesn’t matter.-1*xample%"& A 1250 kg car moves with at a speed of 25 m/s. … Hope this helps! It is not currently accepting answers. *kinetic energy depends on an objects mass and speed . Which has more kinetic energy, the regular car or the race car? 2 Answers. The kinetic energy k of a particle moving along a circle of radius R depends on the distance covered. Kinetic Energy (K.E) = (½)mv 2. m= Mass in Kilograms Kinetic Energy. A. For example, if all the particles in a system have the same velocity, the system is undergoing translational motion and has translational kinetic energy. The kinetic energy of an object depends on both its mass and velocity, with its velocity playing a much greater role. Up Next. The kinetic energy of a particle is a single quantity, but the kinetic energy of a system of particles can sometimes be divided into various types, depending on the system and its motion. answer choices .

The sum in the parentheses depends on the rigid body concerned (its size, shape and mass distribution) and on … SURVEY . A golf club striking a golf ball is a great example of this form of energy. An object’s kinetic energy (*KE*) depends on its mass (*m*) and velocity (*v*). The amount of kinetic energy an object has depends on its. Particles which have more kinetic energy will move faster than particles which have less kinetic energy. Kinetic energy depends on an objects density and speed . (T) only. The race car has more KE because it has a higher velocity. I also have to put, once again, why I chose the answer I choose. Next lesson. Q. Gravitational potential energy depends on the _____ and _____ of the object. What is the kinetic energy of the car? The amount of kinetic energy that it possesses depends on how much mass is moving and how fast … Ans; 2as? So simple explanations are helpful. Kinetic energy is one type of energy store. What is his gravitational potential energy? correct the following statement : The equation used to calculate the kinetic energy is KE = 2 mv2 . In my book given that, Average K.E is independent of pressure, Volume or nature of the gas. If an object is moving, then it possesses kinetic energy. B. Kinetic energy. Viewed 4k times 1. Work-energy theorem. Vibrational Kinetic Energy Vibrational kinetic energy is, unsurprisingly, caused by objects vibrating. Answer Save. * KE = 1 mv 2 ____ 2. solve : mass = 100 kg velocity = 10 m/s. Average kinetic energy of a molecule is = (3/2)kT Avg. 2. It is also important to recognize that the most probable, average, and RMS kinetic energy terms that can be derived from the Kinetic Molecular Theory do not depend on the mass of the molecules (Table 2.4.1). CHRIS Q. Lv … Solution: Above the threshold frequency, the maximum kinetic energy of the emitted photoelectrons depends on the frequency of the incident light, but is independent of the intensity of the incident light so long as the latter is not too high .
