Is drag a contact or a noncontact force?
Drag is a noncontact force. It is a resistive force that acts on an object as it moves through a fluid, such as air or water. Drag force is dependent on an object's shape, size, and speed.
What do you mean by drag forceexplain why objects moving in fluids must have special shape?
Drag force is a resistance force exerted by a fluid (like air or water) on an object moving through it. Objects moving in fluids must have a special shape to minimize drag force and enhance their motion efficiency. The shape is designed to reduce turbulence and separation of flow, which helps the object move through the fluid with less resistance.
What force that slow something down under water?
Drag force slows objects down underwater. This force is caused by the resistance of the water as an object moves through it. Factors such as shape, size, and speed of the object can affect the amount of drag force experienced.
What is drag force and what are its factors on which it depends?
Drag force is the resistance to motion of the object offered by the medium through which it travels, its value depends on the viscosity of the medium, and the shape, size and surface texture of the object. Note: for any given object, the drag force is equal to the square of the velocity * the drag coefficient of the object (rolling resistance is extra in the case of cars etc.)
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 a drag and how does it act on the force of gravity?
Drag is a resistive force that opposes the motion of an object moving through a fluid (like air or water). It acts on the force of gravity by slowing down the object's motion as it falls. The greater the surface area or shape of the object, the more drag it experiences, affecting how quickly it falls due to gravity.
What occurs when an object is moving through a gas or liquid?
When an object moves through a gas or liquid, it experiences drag force, which is the resistance exerted by the fluid on the object. This drag force tends to slow down the object's motion. The amount of drag force depends on the object's shape, size, speed, and the properties of the fluid it is moving through.
The SI unit of the drag force?
If you consider drag as a force, that would be Newtons.If you consider drag as a force, that would be Newtons.If you consider drag as a force, that would be Newtons.If you consider drag as a force, that would be Newtons.
How drag vary with the shape of the object and viscosity of the fluid?
The drag force acting on an object is influenced by its shape and the viscosity of the fluid it is moving through. Objects with streamlined shapes experience less drag compared to those with irregular shapes, as streamlined shapes reduce turbulence. Higher fluid viscosity results in increased drag force, as the fluid resists the object's motion more, leading to more energy being required to overcome this resistance.
How do you minimise the drag force?
You can minimize drag force by optimizing the shape of the object to reduce surface area, smoothing out sharp edges or rough surfaces, and using streamlined designs to minimize turbulence. Another way is to reduce the speed at which the object moves through a fluid, as drag force increases with velocity squared. Finally, utilizing materials with low friction properties can also help reduce drag.
How does the shape of a car make it faster?
the shape of the car is vital when designing because if you want a high speed car then it has to be aerodynamic this makes it easier for the air to go around the car and stops it from having drag drag is the force of the air that is pushing on a car if you want a fast car you need less drag
