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 affect Earth? What is upthrust in forces?
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...
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...
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 ...

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...
When the bird tilts its wings, a centripetal force, a force pushing a body in a circular path, is generated. Due to the change in position of the wings, the lift force changes direction, acting in a perpendicular angle to the bird’s wings. The result of these force shifts is that th...
If the total energy of the molecules isn't changed (no work done), but their speed in a particular direction is, then their movement is a bit less random, with a net increase in movement in the direction of flow, and a net decrease in movment perpendicular to the flow. This req...
No, Centrifugal Force is a fictitious or perceived force due to inertia in a rotating system. 5 Does Centripetal Force act inward or outward in circular motion? Centripetal Force acts inward towards the center of the circular path. 5 Does Centrifugal Force appear to act outward from the center...
