Readers ask: “which Encounters The Greater Force Of Air Resistance, A Falling Elephant Or A Falling Feather?

Why does a feather have more air resistance?

Well, it’s because the air offers much greater resistance to the falling motion of the feather than it does to the brick. The air is actually an upward force of friction, acting against gravity and slowing down the rate at which the feather falls.

When comparing an elephant and a feather The elephant has a greater acceleration because it has more mass?

Even though a baby elephant may experience 100 000 times the force of a feather, it has 100 000 times the mass. The force/ mass ratio is the same for each. The greater mass of the elephant requires the greater force just to maintain the same acceleration as the feather.

Why does the air resistance increase as a skydiver falls?

The cross-sectional area of the skydiver An open parachute increases the cross-sectional area of the falling skydiver and thus increases the amount of air resistance which he encounters (as observed in the animation below). Once the parachute is opened, the air resistance overwhelms the downward force of gravity.

Which will fall faster an elephant or a mouse?

True or False? Free body diagrams of the Elephant and Mouse show that the mouse quickly reaches terminal velocity, (Terminal Velocity occurs when Fg = Fair) while the elephant continues to accelerate for much longer. The elephant is therefore going faster when it hits the water.

What if there was no air resistance?

If there is no air resistance, after you let go of an object the only force on it is the gravitational force. More massive objects have a greater gravitational force. The acceleration of an object is proportional to the net force on the object and inversely proportional to the mass of the object.

Does a feather fall faster than a brick?

Well, it’s because the air offers much greater resistance to the falling motion of the feather than it does to the brick. Air resistance causes the feather to fall more slowly. If a feather and a brick were dropped together in a vacuum?that is, an area from which all air has been removed?

Does a feather fall at the same speed?

The video takes Galileo’s famous experiment to a new level, where both heavy and light objects are dropped at the same time to see which will hit the ground faster. Spoiler: the answer is that they will all fall at the exact same rate. Though some objects, like feathers, seem to fall slower because of air resistance.

Do heavier objects have more air resistance?

heavy objects will have a higher terminal velocity than light objects. It takes a larger air resistance force to equal the weight of a heavier object. A larger air resistance force requires more speed.) Therefore, heavy objects will fall faster in air than light objects.

Which object is most affected by air resistance?

Both elephant and feather have the same force of gravity, yet the feather experiences a greater air resistance. Each object experiences the same amount of air resistance, yet the elephant experiences the greatest force of gravity.

Do heavier skydivers fall faster?

In short: when you skydive, your surface area slows you down, and your mass speeds you up. That’s why small skydivers sometimes wear weights. Someone the same height as you but heavier will have increased mass, and fall faster. Someone the same weight as you but taller will have increased surface area, and fall slower.

What factors affect air resistance?

The amount of air resistance an object experiences depends on its speed, its cross-sectional area, its shape and the density of the air. Air densities vary with altitude, temperature and humidity.

What is the lowest altitude to open a parachute?

The United States Parachute Association sets minimum pack opening altitude at 2,000 feet AGL(Above Ground Level as opposed to MSL — Mean Sea Level) for experienced skydivers, 2,500 feet for slightly less experienced skydivers, and up to 5,500 feet for certain training jumps.

Does Weight Affect falling speed?

The simplest answer is: no, an object’s weight usually will not change its falling speed. For example, you can test this by dropping a bowling ball and a basketball from the same height at the same time–they should fall at the same speed and land at the same time.

What falls faster a pound of feathers or a pound of bricks?

The bricks are more compact and dense and would fall faster than the pound of feathers. The pound of feathers would have so much more surface area and lower density that they would fall much slower than the bricks.

Why do heavier objects not fall faster?

They think that gravity acts more on a heavier object thus pulling it down faster. In fact, gravity works independently of mass. The greater the surface areas of an object the more surface for air to push up against and so air resistance will act upon a falling object, slowing its fall.
