When a skydiver jumps from an airplane the distance d in feet the diver falls in t seconds before opening the parachute is given by the formula Test Image. The formula assumes that there is no air res?
If d = 16*t^2 then there is no significant air resistance.
Does air resistance increase or decrease the acceleration of a falling obect?
Well, the more the air resistance, the lower the acceleration.
When an object falls through the air and encounters air resistance its overall speed will be?
Terminal Velocity. This is the velocity at which the accelaration from Earth's gravity and the drag from air resistance reaches equillibrium.
An airplane flies 500 miles with the wind and 340 miles against the wind in the same length of timeIf the speed of the wind is 40 what is the speed of the airplane in still air?
Air speed or ground speed?
What is an upward force?
It is a force which acts in the upward direction.
How does air resistance help an airplane fly?
Air resistance actually holds an airplane back. It must overcome that resistance to fly.
What is the drag of an airplane?
The drag of an airplane is the air resistance caused by the plane flying through air. Similar to when you pull your hand through water and feel resistance.
What Is Drag On An Airplane?
the force created by air resistance
What is the counter force of an airplane?
Gravity and air resistance.
A free body diagram of a ball falling in the presence of air resistance would show A only a downward arrow to represent air resistance B a downward arrow to represent gravity C neither?
Neither. It would need a downward pointing arrow for the force of the acceleration due to gravity and a second arrow for the air resistance pointing up.
If an airplane lowers the flaps it is decreasing air resistance?
yes
What Forces act on an arrow in air?
When an arrow is in the air, the main forces acting on it are gravity pulling it downwards and air resistance working against its forward motion. These forces affect the arrow's trajectory and speed as it moves through the air. Additionally, factors like wind can also influence the arrow's flight path.
Which force on an airplane can also be called a resistance force?
Drag force on an airplane is often referred to as a resistance force. It is the force that opposes the forward motion of the airplane and is caused by air resistance.
How is an airplane flying an example of fluid friction?
When an airplane is flying, it experiences fluid friction with the air around it. This friction is caused by the resistance of the air to the movement of the airplane. The airplane's design and engine power are optimized to overcome this friction and maintain flight.
Can you put the word air resistance in a sentence?
The sky diver jumped off the airplane and experienced air resistance.
Why does an airplane have to have a pointy nose?
To fight off air resistance and go faster. If the airplane had a flat nose, (like your palm) the air resistance would affect the nose and make the plane slower, while a pointy nose allows the air resistance to pass by therefore making the plane go faster.
How is an aeroplane able to stay in the air if it is heavier than air?
Yes, as long as the surface area of the airplane was large enough to make the force of air resistance balance with the force of gravity or if the airplane is moving at a fast enough speed to make the air resistance balance with gravity.
