Solve the following problems. Because Earth is rotating around its axis, objects on its surface have radial acceleration. Take note that the radius of the Earth is 6,380 km and Earth rotates around its axis in 24 hours. a. What is the radial acceleration of an object at Earth's equator in m/s? b. What is the radial acceleration for an object at 20-degree latitude? c. Express your answers in parts (a) and (b) as a fraction of acceleration due to gravity, g. Using these values, explain why objects on Earth's surface are not thrown off into space.

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
