* Force is a vector quantity: It has both magnitude (how strong it is) and direction.
* Newtons are the unit of force: One Newton (N) is defined as the force required to accelerate a 1 kilogram mass at a rate of 1 meter per second squared (m/s²).
* Centripetal force is a real force: It's the force that keeps an object moving in a circular path. This force is always directed towards the center of the circle.
Examples of forces measured in Newtons:
* The force of gravity pulling you towards the Earth.
* The force you exert when pushing a shopping cart.
* The force a spring exerts when stretched.
* The centripetal force keeping the Earth in orbit around the Sun.
Key takeaway: Centripetal force is just another type of force, and like all forces, it's measured in Newtons.
