The amount of kinetic energy stored in a body depends on its mass and its speed. 8788563422. 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). Particles which have more kinetic energy will move faster than particles which have less kinetic energy. $\begingroup$ @user248881 In the standard model of particle physics all photons are point particles, i,e, have no size. Practice: Using the kinetic energy equation. Using the kinetic energy equation. Definition of potential energy, gravitational potential energy, elastic potential energy and other forms of potential energy. 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). As you increase temp of gas then K.E will also increase. 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. 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 . Translational kinetic energy depends on motion through space. Mon to Sat - 10 AM to 7 PM Kinetic Energy. B. kinetic energy A bowling ball has kinetic energy when it is moving. What is his gravitational potential energy? The kinetic energy of an object depends on two things: the objects _____ and _____. B. c. D. Tags: Question 12 . … Active 4 years, 10 months ago. 2. 2. * KE = 1 mv 2 ____ 2. solve : mass = 100 kg velocity = 10 m/s. Kinetic energy is the energy of motion. You Try%"& 1. Examples of Kinetic Energy: 1. When the particles are moving very fast, we feel the substance and say "That's hot!". The kinetic energy k of a particle moving along a circle of radius R depends on the distance covered. The amount of kinetic energy an object has depends on its. Only velocity. Mass is weight because of how much weight a object has would decrease the speed. I also have to put, once again, why I chose the answer I choose. So simple explanations are helpful. C. Height. C. only velocity. In my book given that, Average K.E is independent of pressure, Volume or nature of the gas. 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. 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? answer choices . SURVEY . D. Mass and velocity. The E=hν. An airplane has a large amount of kinetic energy in flight due to its large mass and fast velocity. Which point has the most kinetic energy, assuming friction and air resistance are negligible? Using the kinetic energy equation. The amount of kinetic energy that it possesses depends on how much mass is moving and how fast … [closed] Ask Question Asked 4 years, 10 months ago. Only mass. An object’s kinetic energy (*KE*) depends on its mass (*m*) and velocity (*v*). The sum in the parentheses depends on the rigid body concerned (its size, shape and mass distribution) and on … 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. Q. Gravitational potential energy depends on the _____ and _____ of the object. Answer Save. Thus, the higher the mass and velocity of a body, the greater the kinetic energy attained. A. It’s essentially the energy of an object due to its vibrational motion. Kinetic energy depends on...? kinetic energy synonyms, kinetic energy pronunciation, kinetic energy translation, English dictionary definition of kinetic energy. 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. B. height. CHRIS Q. Lv … 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. Kinetic energy is one of several types of energy that an object can possess. The amount of kinetic energy an object has depends on the mass of the object and the speed of the object. Kinetic energy is energy a object has while its in motion so the key word is speed. A golf club striking a golf ball is a great example of this form of energy. This is because the temperature of a substance depends on the kinetic energy of the particles. Our mission is to provide a free, world-class education to anyone, anywhere. Viewed 4k times 1. The kinetic energy of a moving object can be calculated using the equation: Kinetic energy = \(\frac{1}{2}\) x mass x (speed) 2. It is not currently accepting answers. The equation for kinetic energy is *KE = ½mv**2*, so the greater the mass and the greater the velocity, the greater the kinetic energy. Yes. In the photoelectric effect, explain why the stopping potential depends on the frequency of the light but not on the intensity. The kinetic energy of an object depends on both its mass and velocity, with its velocity playing a much greater role. Vibrational Kinetic Energy Vibrational kinetic energy is, unsurprisingly, caused by objects vibrating. correct the following statement : The equation used to calculate the kinetic energy is KE = 2 mv2 . Sort by: Top Voted. Kinetic energy is the energy of motion. Calculating kinetic energy. 2 See answers Nonportrit Nonportrit The amount of kinetic energy an object has depends on its "speed." It is given as K E = a s 2, where a is a constant. The race car has more KE because it has a higher velocity. 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. For more such videos please go to http://vidhyasangam.com/Videos.html (T) only. 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. answer choices . The force acting on the particle is Kinetic energy is one type of energy store. D. mass and velocity. The unit for energy is joules. 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. Friction and movement. A spring has more potential energy when it is compressed or stretched. For any content/service related issues please contact on this number . You are very important to us. Kinetic Energy: energy of motion; Depends on: mass, velocity; III. 2 Answers. Up Next. Relevance. Kinetic energy depends on A. only mass. are solved by group of students and teacher of Class 11, which is also the largest student community of Class 11. Kinetic energy review. What is the kinetic energy of the car? This question is off-topic. K.E is directly proportional to temp. 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 + ⋯ ) . If an object is moving, then it possesses kinetic energy. 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. 2 $\begingroup$ Closed.
