What are 10 examples of action-at-a-distance force?
Gravitational force Magnetic force Electric force Nuclear force Electrostatic force Tension force in a rope Friction force Spring force Drag force Buoyant force
What are the different forces acting on a body immersed in a liquid?
When a body is immersed in a liquid, the forces acting on it include buoyant force (upwards force due to displaced liquid), gravitational force (downwards force due to gravity), and drag force (resistance force due to the movement of the body through the liquid).
The Force of an airplane that opposes thrust is called?
The force of an airplane that opposes thrust is called drag. Drag is the resistance force that acts opposite to the direction of motion of the aircraft and is caused by the interaction of the aircraft with the surrounding air.
What is a force that acts in the direction opposite to the velocity of an object moving in air?
Drag force is a force that acts in the direction opposite to the velocity of an object moving in air. It is caused by the resistance of the air against the motion of the object, slowing it down.
What does the word terminal speed?
Terminal speed refers to the constant speed that an object reaches when the drag force acting on it equals the driving force. This means the object no longer accelerates and continues moving at a constant velocity. It occurs when the drag force and gravitational force are balanced.

What is the meaning of drag?
Drag is something that is force exerted. It is a force that is exerted in the opposite direction of movement.
What are the forces acting on a submarine travelling at a constant depth?
When a submarine is traveling at a constant depth, the primary forces acting on it are buoyancy, gravity, drag (or hydrodynamic resistance), and thrust. The buoyant force, which acts upward, is equal to the weight of the water displaced by the submarine, while gravity pulls the submarine downward. For the submarine to maintain a constant depth, these forces must be balanced, meaning the buoyant force equals the gravitational force. Additionally, the thrust generated by the submarine's engines must counteract the drag force to maintain a steady speed.
When a body attains terminal velocity its drag force and gravitational force on body cancels each other then why does the body still comes down instead of floating?
When the gravitational and drag forces on the object are equal, there is no net force acting on the object. This means that the body will not accelerate; it will not change it's velocity.In order for the body to slow down to "floating speed", the drag force would have to be greater than the gravitational force. Drag force is dependent on velocity though, so the greater the velocity the greater the drag. Since the body is not accelerating at terminal velocity, it won't increase it's velocity, and therefore the drag force on it will not increase.(This is all assuming that is a rigid body in an atmosphere with a more or less uniform density, such as a block falling from an airplane.)

What is an example of drag force?
An example of drag force is the resistance experienced by an object moving through a fluid, such as air or water. As the object moves, the drag force acts opposite to its direction of motion, slowing it down. This force is influenced by the object's shape, size, and velocity, along with the properties of the fluid it is moving through.
What is the force that oppose thrust?
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.
What is the force for a soldier parachuting?
The force acting on a soldier parachuting primarily includes the gravitational force pulling them downward and the drag force opposing their fall due to air resistance. As the soldier descends, gravity accelerates them until they reach terminal velocity, where the drag force equals the gravitational force, resulting in a constant speed. The parachute, when deployed, significantly increases drag, reducing their speed and allowing for a controlled descent. Overall, the interplay between these forces determines the soldier's descent rate and safety during landing.
What are three factors at work when an object is placed in a fluid.?
1. Weight of the object acting always downward which is due to gravitational pull 2. Buoyant force which acts always upward which equals to the weight of the displaced fluid. 3. As the objects starts moving within fluid then viscous dragging force comes into the scene and acts always opposite the direction of motion.
