Centripetal acceleration is a vector, which means it has both a magnitude and a direction. The direction always points inward to the circle's center, because this is the direction in which a rotating object is always accelerating. This is often a confusing concept, because an object undergoing ...
a) A plane is going 400 km/hr and turning on a 200 m curve. What is the centripetal acceleration in m/s^2 and in g's? b) If the plane in part a) was flying at the same speed but along a tighter curve, ...
A satellite moves at 8,573 m/s at a radius of 8,500,000 meters from the center of the Earth. What is the centripetal acceleration of the satellite? 0.001 m/s/s 8.65 m/s/s 9.8 m/s/s 0 m/s/s Explain What is angular distanc...
A 0.8 kg mass attached to a 2.9 m long string is whirled around in a horizontal circle at a speed of 7 m/s. What is the centripetal acceleration of the mass? A rotating disk has a mass of 0.51 kg, a radius of 0.22 m and an angular speed of 0.40 rad...
The vector is itself perpendicular to Q. The theorem allows the calculation of the rate of change of Q (which is its derivative, since the magnitude of Q is constant) without resorting to calculus. In addition, a geometric argument allows calculation of the direction of the rate of change ...
What are Forces？(力的相互作用-美国康菲尔高中)
Is centrifugal force real? While centripetal force is an actual force, centrifugal force is an apparent force. In other words, when you twirl a rock tied on a string, the string exerts an inward centripetal force on the rock, while from the rock's point of view, there appears to be an...
Torque is the twisting force that tends to cause rotation. It is the measure of how much a force acting on an object causes that object to rotate. Visit to learn how to calculate torque along with its formula, meaning and applications.
Centripetal Acceleration Formula Another common calculation is centripetal acceleration, which is the change in velocity divided by the change in time.Acceleration isthe square of velocity divided by the radius of the circle: Δv/Δt = a = v2/r ...
The centripetal acceleration essentially simulates higher gravity, however, it's important to keep in mind the artificial gravity is a range of values, depending on how close an object is to the axis of rotation, not a constant value. The effect is greater the further out an object gets bec...
