Examples: 1. A boat travelling in water. 2. An aeroplane moving in the sky.
Also, what are the different types of drag force?
Drag – Types and Effects
- Drag.
- Induced Drag.
- Parasite Drag.
- Interference Drag.
- Form Drag.
- Friction Drag.
- Wave Drag.
- Surface Coatings and Drag Reduction.
Subsequently, what is an example of a resistant force?
Friction and fluid resistance are resistive forces when the material is stationary. However, both can also contribute as an applied force when the materials or objects are moving relative to each other. For example, a boat moving through still water experiences the resistive force of water resistance.
What is drag force Class 8?
The frictional force exerted by a fluid is called drag.
Drag is a kind of frictional force exerted by fluid which opposes the motion of an object through that fluid. Drag force acts in direction opposite to the direction of motion of the object.
What is drag force equal to?
a = (W – D) / m. The drag force depends on the square of the velocity. So as the body accelerates its velocity and the drag increase. It quickly reaches a point where the drag is exactly equal to the weight. When drag is equal to weight, there is no net external force on the object, and the acceleration becomes zero.
What is drag force in physics?
Drag is a mechanical force. It is generated by the interaction and contact of a solid body with a fluid (liquid or gas). It is not generated by a force field, in the sense of a gravitational field or an electromagnetic field, where one object can affect another object without being in physical contact.
What is drag force in simple words?
Drag is the aerodynamic force that opposes an aircraft’s motion through the air. Drag is generated by every part of the airplane (even the engines!). How is drag generated? Drag is a mechanical force. It is generated by the interaction and contact of a solid body with a fluid (liquid or gas).
What is sliding friction example?
Examples of Sliding Friction
Rubbing both the hands together to create heat. A child sliding down through a slide in a park. A coaster sliding against a table. A washing machine pushed along with the floor.
Which answer is an example of drag?
Answer: Air resistance is an example of the drag force , which is force that objects feel when they move through a fluid (liquid or gas).
Who discovered drag force?
| Sir George Cayley Bt | |
|---|---|
| Nationality | English |
| Citizenship | British |
| Known for | Designed first successful human glider. Discovered the four aerodynamic forces of flight: weight, lift, drag, thrust; and cambered wings, basis for the design of the modern aeroplane. |
