Force is a vector. We get force from time derivative of momentum and momentum is a vector because velocity is a vector which is time derivative of displacement which is again a vector. In simple words-force has both magnitude and direction and hence it is a vector quantity.
It is the force that allows satellites, including natural ones like the moon, to stay in orbit around the Earth, and the Earth to stay in orbit around the sun. The most basic equation for force is: force equals the mass of an object multiplied by its acceleration. To calculate the force of Earth's gravitational field, acceleration is substituted with the measured acceleration of gravity, which is 9.81 meters per second squared.
