The kinetic energy K of a particle moving in a straight line depends on the distances as K=as2. The force acting on the particle is (where a is a constant) View Solution The force acting on a particle moving along a straight line varies with time as shown in diagram. Which of ...
The kinetic energy of a body depends Aon its mass only Bon its speed only Con its mass as well as on its speed Dneither on its mass nor on its speedSubmit The kinetic energy of rolling body is A1/2Iω2 B1/2Iω2+1/2mv2 C1/2mv2 D1/2mR2Submit The shape of the curve represe...
Let us now determine the kinetic energy of a rotating body. To do so, we imagine it divided into parts so small that they may be regarded as moving like particles. Ifmiis the mass of theith part andriits distance from the axis of rotation, then its velocity isvi=riΩ, where Ω is t...
Learn the concept of the kinetic and potential energy of a body. See the formulas of kinetic and potential energy and learn how to use these...
9.Thiskinetic energydepends on the mass of the object and how fast it's moving. 这个动能取决 的质量和它移动的速度。 「Crash Course 天文篇」评价该例句:好评差评指正 PBS趣味 10.Temperature is really a measure of all that jiggling, thekinetic energyof anything's atoms. ...
(General Physics) the energy of motion of a body, equal to the work it would do if it were brought to rest. Thetranslational kinetic energydepends on motion through space, and for a rigid body of constant mass is equal to the product of half the mass times the square of the speed. ...
Another possibility would be for the cyclist to apply the brakes, in which case the kinetic energy would be dissipated through friction as thermal energy.Like any physical quantity which is a function of velocity, the kinetic energy of an object depends on the relationship between the object and...
Learn what kinetic energy is and identify types of kinetic energy. Discover the equation for calculating the energy of motion and examine kinetic...
The SI unit for KE is the Joule (J) where 1 J = 1 Nm. The heavier the mass and the faster it is moving, the more kinetic energy it has, but it depends linearly on the mass while scaling with the square of the speed. ...
where m is the mass of the body and v is its velocity. 2. Analyze the Effect of Mass on Kinetic Energy: According to the formula, kinetic energy is directly proportional to the mass of the body when the velocity is constant. This means that if the mass m increases, the kinetic energy...
