Approximating the orbit as perfectly circular, find the centripetal acceleration of Earth. Assumptions: Orbital radius (distance from the Sun to Earth) is \(1.50\times 10^{11} \text{m}.\)
2 Ιουν 2018 · Determine your centripetal acceleration due to rotation of the Earth. The geographical latitude of Toronto is $\Phi=43^{\circ}$. Radius of the Earth is $R=6.38\cdot 10^6$m.
Centripetal acceleration \(a_c\) is the acceleration experienced while in uniform circular motion. It always points toward the center of rotation. It is perpendicular to the linear velocity \(v\) and has the magnitude \[a_c = \dfrac{v^2}{r}; \, a_c = r\omega^2. \nonumber \]
The centripetal acceleration is about 3.39 cm/sec^2 at the equator (I m getting this number from the CRC Handbook of Chemistry and Physics), which is about 0.35% the acceleration of gravity at the surface of the earth, g.
The first term on the right is the acceleration in the Earth reference frame. The remaining terms are the apparent accelerations. The first one is the Coriolis acceleration and the second one is the centripetal acceleration.
11 Οκτ 2024 · The centripetal acceleration a c has a magnitude equal to the square of the body’s speed v along the curve divided by the distance r from the centre of the circle to the moving body; that is, a c = v 2 /r. Centripetal acceleration has units of metre per second squared.
