What do force, velocity, and momentum have in common? Force equals mass times When the velocity of an object is quadrupled, by what factor is its momentum changed? At what speed should a ball of mass 2 kg travel so that it has a kinetic energy of 500 J? What is the mass of an ob...

Velocity=dXdt=X=−ωX0sin(ωt)Acceleration=d2Xdt2=X=−ω2X0cos(ωt) Inserting the above expression for acceleration, or d2X/dt2, into the equation for Fs yields the following: Mgcd2Xdt2+KX=0−Mgcω2X0cos(ωt)+KX=0−Mgcω2X+KX=−Mgcω2+K=0 Solving this expression for ω...
Velocity always has a direction. Velocity=Distance/time with direction Δ=Change in Average velocity=ΔPositionTime=DisplacementTime Acceleration Acceleration is the rate of change of velocity of an object. It can be positive or negative. Acceleration equals the change in velocity divided by the ...

Once you have started the boulder rolling, it develops momentum, which is defined by itsmassand velocity. 出自-2015年12月阅读原文 In terms of efficiency and cleanness, buses, trains and other form of public ormasstransportation are superior to the private automobile. ...
In order to compensate the difference in velocity, an energy focusing device: reflectron, normally an electrostatic mirror, is placed at the end of the ToF analyser. Ions with higher velocity will penetrate further into the reflectron, thus ions with different kinetic energy will reach the ...
With the mass sliding in the positive direction, the frictional force is f=FCoulomb+Fpropv+FStribeckexp−fexpv When the velocity goes to zero, the mass becomes stuck. It resumes sliding when the magnitude of the applied force exceeds the maxi...
【题目】Consider a particle of mass m moving in two dimensions between two perfectly reflecting walls which intersect at an angle x at the origin (see Figure). Assume that when the particle is reflected, its speed is unchanged and its angle of incidence equals its angleof reflection. T he ...
