Question

what is external force in gravity

Answer 1

our purpose we will only say that external force is applied force , normal force, tension force, frictional force , and a resistance force .and for our purpose , the internal force includes the gravity force , magnetic force ,electrical force, and spring force .

Answer 2

Answer:

External forces are forces resulting from the interaction between human body and its environment. External forces can be divided into contact forces and non-contact forces. Most forces that biomechanics works with are contact forces. ... Gravitational force, acting on all objects on the Earth, is a non-contact force.

Newton's second law states that the magnitude of the net external force on an object is Fnet=ma. Since weight g=9.80m/s2 on Earth, the weight of a 1.0 kg object on Earth is 9.8 N, as we see: w=mg=(1.0kg)(9.8m/s2)=9.8N.

When a system of particles or a rigid body is being considered as a whole, an external force is a force acting on the system from outside. Compare internal force.
