Height, mass and gravitational strength. I also have to put, once again, why I chose the answer I choose. 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. Only velocity. Using the kinetic energy equation. Kinetic energy review. For any content/service related issues please contact on this number . A. Yes. As such, it can be concluded that the average kinetic energy of the molecules in a thermalized sample of gas depends only on the temperature. What is the kinetic energy of the car? The kinetic energy of an object depends on both its mass and velocity, with its velocity playing a much greater role. III. In the photoelectric effect, explain why the stopping potential depends on the frequency of the light but not on the intensity. 2 $\begingroup$ Closed. D. mass and velocity. Kinetic energy depends on the mass and velocity of the body in motion, with the velocity contributing more to the overall kinetic energy of the body. It is given as K E = a s 2, where a is a constant. kinetic energy A bowling ball has kinetic energy when it is moving. 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. You are very important to us. The sum in the parentheses depends on the rigid body concerned (its size, shape and mass distribution) and on … 2 Answers. Mass is weight because of how much weight a object has would decrease the speed. (T) only. Kinetic energy depends on A. only mass. Vibrational Kinetic Energy Vibrational kinetic energy is, unsurprisingly, caused by objects vibrating. The unit for energy is joules. [closed] Ask Question Asked 4 years, 10 months ago. Which has more kinetic energy, the regular car or the race car? 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 . B. c. D. Tags: Question 12 . When the particles are moving very fast, we feel the substance and say "That's hot!". The force acting on the particle is Next lesson. … Ok, so the kinetic energy of an object is supposed to be proportional to the mass of the object, and to the square of the speed of the object, and speed is basically the magnitude of velocity, right? C. only velocity. 2. The stopping potential depends on the kinetic energy of the electrons, which is affected only by the frequency of incoming light and not by its intensity. The amount of kinetic energy that it possesses depends on how much mass is moving and how fast … Using the kinetic energy equation. Kinetic energy depends on...? 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. Sort by: Top Voted. Answer Save. CHRIS Q. Lv … 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. Ans; 2as? Kinetic Energy. K.E is directly proportional to temp. answer choices . If an object is moving, then it possesses kinetic energy. The kinetic energy is then 1 2 m i v i 2, and summation gives the total kinetic energy of the body: E kin = 1 2 m 1 v 1 2 + 1 2 m 1 v 2 2 + ⋯ = 1 2 Ω 2 ( m 1 r 1 2 + m 2 r 2 2 + ⋯ ) . Our mission is to provide a free, world-class education to anyone, anywhere. Define kinetic energy. Which point has the most kinetic energy, assuming friction and air resistance are negligible? Kinetic energy is the energy of motion. Examples of Kinetic Energy: 1. 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. Which would hurt more, getting hit by a 15 foot wave or a 2 foot wave? For more such videos please go to http://vidhyasangam.com/Videos.html The kinetic energy of a moving object can be calculated using the equation: Kinetic energy = \(\frac{1}{2}\) x mass x (speed) 2. The E=hν. D. Mass and velocity. Up Next. Kinetic energy depends on an objects density and speed . *kinetic energy depends on an objects mass and speed . So simple explanations are helpful. * KE = 1 mv 2 ____ 2. solve : mass = 100 kg velocity = 10 m/s. Kinetic energy is one of several types of energy that an object can possess. It is the energy stored in a moving body. As you increase temp of gas then K.E will also increase. correct the following statement : The equation used to calculate the kinetic energy is KE = 2 mv2 . Friction and movement. The amount of kinetic energy an object has depends on the mass of the object and the speed of the object. C. Height. Kinetic energy definition, the energy of a body or a system with respect to the motion of the body or of the particles in the system. Work-energy theorem. Calculating kinetic energy. The kinetic energy of an object depends on two things: the objects _____ and _____. Relevance. The amount of kinetic energy an object has depends on its. The kinetic energy k of a particle moving along a circle of radius R depends on the distance covered. answer choices . Kinetic Energy (K.E) = (½)mv 2. m= Mass in Kilograms 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). Potential energy, stored energy that depends upon the relative position of various parts of a system. Kinetic energy is the energy of motion. It’s essentially the energy of an object due to its vibrational motion. An object’s kinetic energy (*KE*) depends on its mass (*m*) and velocity (*v*). An airplane has a large amount of kinetic energy in flight due to its large mass and fast velocity. The race car has more KE because it has a higher velocity. A. Definition of potential energy, gravitational potential energy, elastic potential energy and other forms of potential energy. Thus, the higher the mass and velocity of a body, the greater the kinetic energy attained. Average kinetic energy of a molecule is = (3/2)kT Avg. 2 See answers Nonportrit Nonportrit The amount of kinetic energy an object has depends on its "speed." 2. Translational kinetic energy depends on motion through space. B. A golf club striking a golf ball is a great example of this form of energy. It is not currently accepting answers. This question is off-topic. Kinetic energy is energy a object has while its in motion so the key word is speed. SURVEY . Practice: Using the kinetic energy equation. You Try%"& 1. Viewed 4k times 1. Mon to Sat - 10 AM to 7 PM For example, if all the particles in a system have the same velocity, the system is undergoing translational motion and has translational kinetic energy. See more. Kinetic Energy. Only mass. Kinetic Energy: energy of motion; Depends on: mass, velocity; III. 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). Active 4 years, 10 months ago. 5,000 J. solve : … Q. Gravitational potential energy depends on the _____ and _____ of the object. Hope this helps! What is his gravitational potential energy? Does the kinetic energy change depending on the direction of the velocity? Kinetic energy is one type of energy store. The equation for kinetic energy is *KE = ½mv**2*, so the greater the mass and the greater the velocity, the greater the kinetic energy. Particles which have more kinetic energy will move faster than particles which have less kinetic energy. This is because the temperature of a substance depends on the kinetic energy of the particles. In my book given that, Average K.E is independent of pressure, Volume or nature of the gas. The amount of kinetic energy stored in a body depends on its mass and its speed. Kinetic energy. kinetic energy synonyms, kinetic energy pronunciation, kinetic energy translation, English dictionary definition of kinetic energy. If you count the reduction in kinetic energy of the train together with the increase in kinetic energy of the ball, the sum is the same regardless of what reference frame you choose.
