When thrust and drag are equal why does the object still move?

When the forces on an object add up to zero, the object's acceleration is zero. That
means the speed or direction of its motion doesn't change. It does not mean that
the object isn't moving. A moving object would just keep moving at a constant
speed in a straight line.

If drag and thrust are equal a flying device will stop?
If drag and thrust are equal, a flying device will stop ACCELERATING, that is it will maintain a constant speed.From classical Newtonian physics:Force = mass x accelerationSince drag and thrust are forces, we have:Thrust - drag = mass x accelerationSince you say that drag and thrust are equal, and the mass of a flying object is some finite value, it turns out that the acceleration = 0, i.e. a constant speed
How drag and thrust can be equal?
The thrust is the force moving something forward. The drag is air resistance applying force in the other direction. Drag will increase when an object moves faster because it will hit more molecules (of air, water, whatever) per second. If you apply constant thrust (force) to an object in air (for example an airplane) it will accelerate until the drag is equal to the thrust at which point it stops accelerating but keeps going at the same speed.
What happens if thrust is greater than drag?
The car (or plane/whatever else it is) accelerates. This means that it gains speed
When is thrust greater than drag?
The object accelerates.
What are the basic requirement's for an object to maintain flight?
Lift, Thrust and Drag
Does drag always make objects faster?
No, drag actually slows the object down but thrust makes it go faster.
How do thrust and drag relate?
Thrust is the FORCE that is trying to propel an object into Motion. Generally it is related to Jet or Rocket engines, but can be a measure of a propeller as well. Drag is the Force generated on the object by the Fluid that it is moving through, such as Water or Air. It is usually in direct relation to the shape of the object.
Does Drag always makes objects go faster?
No, drag actually slows the object down but thrust makes it go faster.
What causes a force to produce motion?
To move an object forward from rest the thrust of forward force must be greater than the drag acting in the opposite direction. In order to keep moving at a constant velocity the forward force must equal the drag.
How does the lift thrust drag and gravity affect a helicopter?
Lift, thrust, drag, and gravity affects all flying objects and wildlife. The blades of the helicopter provide lift, drag and thrust.
Does a hot air balloon depend on thrust or drag?
thrust and drag, because with out thrust the hot air balloon would not be able to move forward and with out drag it would not be able to stop
What are the four forces that act on an airplane in flight?
Lift, weight, thrust and drag.
