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.
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.
When the thrust force is equal to the drag force, the object will maintain a constant velocity (assuming no other forces are acting on it). This state is known as dynamic equilibrium, where the forces are balanced and there is no acceleration.
Thrust is the force produced by an engine to propel an object forward. To overcome drag, an object must generate enough thrust to balance out the drag acting in the opposite direction. By increasing thrust or reducing drag, an object can achieve a higher speed or maintain steady motion in the presence of drag forces.
The car (or plane/whatever else it is) accelerates. This means that it gains speed
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
The object accelerates.
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.
Thrust is the force that counteracts drag. Thrust is generated by engines, propellers, or other propulsion systems to overcome the resistance caused by drag and move an object forward.
Lift, Thrust and Drag
Drag is the force that opposes thrust. It is a resistive force exerted on an object moving through a fluid, such as air or water. Drag acts in the opposite direction to the motion of the object and slows it down.
Friction is a force that opposes the motion of an object. In the context of thrust, friction between the object and its surrounding surfaces can reduce the efficiency of the thrust by creating drag or resistance. Minimizing friction can help increase the effectiveness of thrust in moving an object.
No, drag actually slows the object down but thrust makes it go faster.
