Best blade angle?
the best angle is "45 degree" because the air speed coming out of the fan is giving by this equation V=v.tanθ were : V: air speed,,, v: is the blades speed and we got the maximum of the speed by making the angle 45
The speed of ball increases as it rolls down an inclinem What happens to its speed on a smooth horizontal surface?
It's speed will reduce to to friction by gravity.
How does drag work?
Drag force, or the force of air friction for a falling body, increases with speed. A falling object will reach a speed at which the force of air friction will be equal to and opposite the force of gravity. At that point, the object will no longer accelerate. It's speed will remain constant, and we call that speed (and direction) its terminal velocity.
What is the horizontal velocity of 25 degrees?
Multiply the speed by the cosine of the angle (25 degrees in this case). For the vertical velocity, multiply by the sine of 25 degrees.Multiply the speed by the cosine of the angle (25 degrees in this case).

How will the angle of a ramp affect the speed of a car going down it?
The larger the angle of the ramp, the faster the car will go down it.
Would friction or air pressure affect how fast a ball rolls down a incline?
Yes it would. Speed will depend on Weight of the ball, Incline angle, Friction, and air pressure.
How you can improve bowling speed?
get more arm power or get the right angle
How does friction effects speed?
Friction will reduce an object's speed.
How does friction alter speed?
If there is friction, speed will usually be slowed down.
When using the inclined plane what is the push or pull force?
(ignoring friction) > Mass of the object * sine (incline angle) = force down, and parallel to, the slope (kilograms force) This ratio ( force / mass) remains constant regardless of the objects mass, as long as the incline angle remains the same.
Effect of speed on the force of friction?
Friction is independent of speed once an object is moving since faster does not mean more friction.
Does speed affect the friction between a road and a skidding tire?
Speed does not affect the force of friction.
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.
How can you measure rolling resistance?
Roll the object down an inclined plane. Adjust the angle so that the objects rolls down without sliding at a constant speed. When that happens, the tangent of the angle of the plane relative to the horizontal is the coefficient of rolling friction.
Is friction a greater force when motion is faster?
Friction is not affected by the speed of motion. The force of friction remains constant regardless of the speed of the objects in contact.
Does friction speed up an object?
Friction does not speed up an object; it creates drag and slows it down.
What affect does friction have on speed?
Friction tends to slow down an object's speed by opposing its motion. It transforms the kinetic energy of the object into heat, which dissipates into the surroundings. The greater the friction, the greater the decrease in speed.
