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 an applied force move? A car moving at 72 m/s drives off a cliff that is 200 m high. a. What is the velocity of the car as it hits the ground? b. How long does it take for the car to hit the ground? c. How far away from the ...
In which direction does centripetal force point? A target T lies flat on the ground 3 \ m from the side of a building that is 10 \ m tall. A student rolls a ball off the horizontal roof of the building in the direction of the target. Air ...

A 0.027 kg ball is shot from the plunger of a pinball machine. A centripetal force of 0.1 N acts on the ball, causing it to move in a circular path of radius 0.2 m. What is the speed of the ball? Does centripetal force have direction?
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 only...
Was it possible to interpret the function of these valves in another way, according to which the bloodstream has the opposite (centripetal) direction? In a world of antelopes, Harvey managed to see a pelican. Figure 6: Harvey interpreted the function of the vein-valves in the opposite way ...
“suspended animation” to detect the speed, direction, and nuances being delivered by the pitch before he abruptly lunges forward and down to plant the foot to begin the swing. If the plant is too early, he’s out in front of the pitch and loses much of his power. If he is late ...
If a pipe is rotated around a point while liquid is flowing through it (toward or away from the center of rotation), that fluid will generate an inertial force (acting on the pipe) that will be at right angles to the direction of the flow. Figure 1: The Coriolis Principle With ...
