Answer:
Gravity
Step-by-step explanation:
For a space station in orbit, the centripetal force is the force of gravity.
For a child in a swing, the centripetal force is the normal force.
For a ball on a string, the centripetal force is the tension.
Gravity is one of four fundamental forces in nature. The other fundamental quantities are the electromagnetic interaction force, the weak force and the strong force. Simply put, gravity is the magnitude responsible for defining the weight of a body, being the centripetal force of orbiting objects (such as a space station, for example) and being the vertical and downward force that holds us together with the planet. Any object that moves in free fall is under the influence of gravity acceleration, which on Earth equals approximately 9.8 m / s2.
