After rounding to three significant figures, the velocity equals 0.914 m/s. We can also rewrite the result with a different unit. Work out the square root of the previous outcome to get the velocity, v = √9 = 3 ft/s To do so, multiply both sides of the equation by r and divide by m Rearrange the centripetal force formula to estimate the square of velocity. Let's find the velocity of an object that travels around the circle with radius r = 5 ft when the centripetal force equals 3.6 pdl. We can also write the solution using scientific notation, F = 3.125×10⁴ N, or with a proper suffix, F = 31.25 kN. How to calculate the centripetal force acting on a car that goes around a circular track? The car's mass is 2 t, its velocity equals 45 km/h, and the radius of the track is 10 m:īefore we do the computations, let's convert the mass to kilograms and switch the speed units from km/h to m/s. Having the theory in our minds, let's try to solve a few centripetal force examples. How to distinguish between them? Let's take a look at the two diagrams with the comparison of centripetal vs. It isn't always evident whether we're dealing with an inertial or non-inertial frame of reference. The second one is the centrifugal force – the representative of the force of inertia.Īs you can see, the centripetal force is present in both reference frames, while the centrifugal force unveils only in the non-inertial one. Once again, there is the centripetal force acting towards the rotation center. In a non-inertial reference frame (the kid's point of view), there are two corresponding forces of the same values that balance each other. Enter three values at start speed, end speed, time and acceleration. In an inertial reference frame (a parent watching the kid from a distance), there is only one force that changes the movement direction – the centripetal force IMPRINT Calculation of the g-force at accelerating or braking in a straight line motion. Imagine a circular motion, e.g., a kid on a merry-go-round: where: F is the spring force (in N) k is the spring constant (in N/m) and x is the displacement (positive for elongation and negative for compression, in m). The formula to calculate the applied force in Hookes law is: F -kx. Then the applied force is 28N for a 0.7 m displacement. The crucial factor that helps us distinguish between these two is the frame of reference. Lets consider the spring constant to be -40 N/m. ![]() Our centrifugal force calculator uses precisely the same equation as for the centripetal one: At first glance, it may seem that there is no difference between centripetal and centrifugal force. ![]()
