What forces act on a pendulum? In the centripetal force equation, what is the mass equal to? Is centripetal force caused by friction? In which direction does centripetal force point? Does the centripetal force
求向心力的公式就是向心力(centripetal force)没错,答得好再加悬赏分 真正问题是:what forces act on you were you at the centre of the earth? 相关知识点: 试题来源: 解析 向心力是没有公式的!有公式就是骗人的!为什么呢?因为向心力的定义就是: 作圆周运动的物体,它运动的时候的合力指向圆心,这个合...
What direction does the acceleration vector point in uniform circular motion? Define centripetal force Is there centripetal force in uniform circular motion? An object's moment of inertia is 1.50 kg.m^2. Its angular velocity is increasing at the rate of 3.30 rad/s^2. What is the net torque...
Water exerts a force on the bottle in upward direction. Now release the bottle. It bounces back to the surface. Does the force due to the gravitational attraction of the earth act on this bottle? If so, why doesn't the bottle stay immersed in water after it is released ? View ...

What is the resulting force the pilot feels when they just begin to pull up into the circle (they are at the lowest point)? Centripetal and Centrifugal Force In physics, centripetal force is the force the keeps a m...
An Orbit is a velocity of direction, a vector of tangential motion, that allows gravitating objects to avoid falling into each other. They circle around the centre of gravity of the ‘system’ they are part of, but here is an important point, not generally recognised at this time… Not ...
We have two forces, the centripetal force pushing up toward the imaginary center of this curved section, and the force of gravity. Use the centripetal acceleration, a = v2/r. At the bottom of the ride, the acceleration is 90 degrees in direction from the speed, (i.e. straight up) whic...
In which direction does centripetal force point? How do you draw the component forces on a mass that is on an inclined plane? What direction does the acceleration vector point in uniform circular motion? Suppose you exert a force of 157157 N tangential to a 0.2740.274-m-radius 7272-kg grin...
(centripetal) direction? In a world of antelopes, Harvey managed to see a pelican. But even researchers and clinicians that belong to the same paradigm may have problems when they compare their observations. Even persons who embrace the same paradigm apply the same methodology, and study the ...
