Seville has the only inland port in Spain, located 80 km (50 mi) from the mouth of the Guadalquivir River. This harbour complex offers access to the Atlantic and the Mediterranean, and allows trade in goods between the south of Spain (Andalusia, Extremadura) and Europe, the Middle East and North Africa.
Centripetal force. The centripetal force is the force that causes an object to move in a circle, acting towards the centre of the circle. In the case of a satellite the centripetal force is gravity, in the case of an object at the end of a rope, the centripetal force is the tension of the rope.
The force that pulls an object out of a straight-line path and into a. circular path is called a centripetal force. The magnitude of the centripetal force required to keep an object in a circular path depends. on the inertia (or mass) and the acceleration of the object, as you know from the second law. (F = ma). The acceleration of an object moving in uniform circular motion is a = v2/r, so the. magnitude of the centripetal force of an object with a mass (m) that is moving with a velocity (v) in a. circular orbit of radius (r) can be found from. The distance (circumference) around a circle is 2Ïr.
