Here's the breakdown:
* Force: A push or pull that can change an object's motion.
* Mass: The amount of matter an object contains.
* Acceleration: The rate of change of velocity over time.
This relationship is described by Newton's Second Law of Motion:
Force (F) = Mass (m) x Acceleration (a)
F = m * a
Velocity is the speed and direction of an object, and while it's related to force and acceleration, it's not directly used to calculate force.
