Friction and drag

Drag

The force opposing the motion of an object through a fluid medium like air or water.

Surface

Interaction between body surface and the fluid, affecting drag.

Form

Resistive forces due to the shape of an object, influencing drag.

Wave

Opposing force caused by waves in the fluid, impacting drag.

Friction

Force exerted by a surface as an object moves across it.

Static Friction

Force resisting the movement of an object in contact with another surface.

Kinetic Friction

Force between objects sliding against each other.

Coefficient of Friction

Constant based on surfaces in contact, affecting friction.

Advantages of Friction

Benefits like shaping objects and aiding movement.

Disadvantages of Friction

Drawbacks such as wear and tear and energy loss.
