Question

Answer the following questions in 1 or 2 sentences.
What happens when the forces are applied on an object in the same direction?
Define drag​

Answer 1

a ) When two forces act in the same direction, they add together. ... Unbalanced forces acting on an object will change the object's motion. Unbalanced forces can also stop a moving object. The three main forces that stop moving objects are friction, gravity and wind resistance.

b ) For a solid object moving through a fluid or gas, drag is the sum of all the aerodynamic or hydrodynamic forces in the direction of the external fluid flow. It therefore acts to oppose the motion of the object, and in a powered vehicle it is overcome by thrust.
