What is the resistance of air to a moving object?
drag friction
Why is rolling an object easier than dragging an object?
Less friction/drag .
When an object moves through a fluid?
drag or air resistance
Can atmospheric pressure affect an object's velocity?
Yes. It's called "drag" and "friction".
How does motion of an object change over time?
Its velocity is reduced as a result of friction and drag.
How does streamlining reduce drag?
Force streamlining reduces air resistance or air friction.
What features will your car have to reduce the forces of friction and drag?
A car will have aerodynamic features to reduce forces of friction and drag. A sleek body style will help do this.
What is the friction drag?
Friction drag is the drag acting on the surface of an object from a fluid flowing over it. When a fluid flows over an object it exerts a shear force on the object because of the fluid's viscosity which pulls the object in the direction of the flow.

Does friction speed up an object?
Friction does not speed up an object; it creates drag and slows it down.
What is drag envelope?
The drag envelope is the space around a moving object that causes friction, pushing in the opposite direction of where the object is going.
What force do skin tight ski pants reduce?
air drag
What is frictional drag?
Friction drag is the drag acting on the surface of an object from a fluid flowing over it. When a fluid flows over an object it exerts a shear force on the object because of the fluid's viscosity which pulls the object in the direction of the flow.
Why does friction never speed up object?
You may be thinking of drag instead of friction. Friction between the floor and your foot increases your speed.
When an object moves through a fluid?
drag or air resistance
Are airplanes designed to reduce or increase drag?
Airplanes try to reduce drag so they can cut back on fuel costs, and shave time off their route.
