I'm not exactly sure, but i think it is called kinesiology.
There are many forces acting on a body. But, the moves because of the net force acting on it. So, we can say that the body accelerates because of net force acting on it only.
A body in uniform motion has no net force acting on it. That means that either there are no forces at all, or else that all the forces acting on it add up to zero.
The body accelerates.

Gravity.
The way in which a body moves when under the influence of gravity, and possibly other forces, requires the study if vector calculus. The net forces cause acceleration in the motion. The velocity of the body is the integral of the acceleration and displacement is the integral of velocity.
The forces acting on a falling body are gravity and air resistance.
The force is said to be "equilibrant" when acting with other forces it would keep the body at rest ie in equilibrium. Hence equilibrant would be equal in magnitude but opposite in direction to the resultant of all the forces acting on the body.
There can well be forces acting on the body. It means that the NET FORCE (the vector sum of all the forces) acting on the object is zero.
1.a buoyant force acting on the body upwards due to air . 2.the weight of body acting downwards . this two forces acts.....
zero
The study of the forces exerted by air on a moving object is officially called aerodynamics.
