Motion of the Air Like lift, drag actually varies with the square of the relative velocity between the object and the air. The inclination of the object to the flow also affects the amount of drag generated by a given shaped object.
Q. Why does it feel more comfortable to catch a hard baseball with a glove rather than with your bare hand explain in physics terms?
Following Newton’s second law, if the ball is caught with the pocket of the glove, it is given more time to decelerate and therefore will have a smaller final acceleration. With this smaller acceleration, the glove, and therefore the player, will have to deal with less force with a glove than without one.

Q. What force counteracts drag?
Thrust
Q. Can drag be reduced?
Interference drag can be minimized by using fairings to ease the airflow transition between aircraft components.
Q. What is the difference between surface drag and form drag?
Smooth skin reduces skin friction drag and thereby improving the performance and fuel efficiency. Form drag: The drag created due to the shape and area of the cross-section of the solid body moving through the fluid. This is created due to the viscous flow to be faced with an adverse pressure gradient.
Q. What are the two main types of drag?
Drag is the force that resists movement of an aircraft through the air. There are two basic types: parasite drag and induced drag. The first is called parasite because it in no way functions to aid flight, while the second, induced drag, is a result of an airfoil developing lift.
Q. How can you reduce drag on something moving through air?
Answer:
- Make it more streamlined.
- Reduce it’s speed (very effective )
- Reduce it’s cross-sectional area.
- Add boundary layer blowing.
- Suck the boundary layer.
Q. How can you reduce drag on something moving through air class 8?
The fluid friction or drag can be reduced are minimised by giving special shape called streamlined shape to the objects which Move through fluids like air or water .
Q. What is drag give two examples of a drag force How can we reduce the drag on something moving through the air?
Answer. To increase drag, the plane can have many flaps it can lift vertically, which will help it increase the drag on the airplane, which is useful to help the plane decelerate or roll. To decrease drag, the plane needs to be streamlined, in a tear drop shape, but not so much so as to create too much friction drag.
Q. What is drag give two examples of a drag force How can you reduce the drag of something moving through the air?
when a airplane move it need to be streamline body to reduce drag because due to high speed air offer a resistance against the motion of plan. 2. Boat in water. 3.
