The net force on a rock that has a force of 4.9N down and 2.8N up applied to it is 2.1N down.
Define force.
A force is an effect that can alter an object's motion according to physics. An mass-laden object can change its velocity, or accelerate, as a function of a force. An obvious method of describing force is as a push or a pull. A force is a vector quantity because it possesses both magnitude and direction.
Thrust, which increases an object's velocity; drag, which decreases an object's velocity; and torque, which causes changes in an object's rotational speed, are all concepts connected to force. Each part of an extended body often exerts stresses on the sections that are nearby.
