What force is acting in the opposite direction to the force of gravity when you drop the helicopter/parachute? (Answer: Drag)

## What forces act on a paper helicopter?

The spinning is caused by the force of air acting on each of the helicopter’s blades. The air presses on each of the blades with an equal force but in the opposite direction and the helicopter spins around.

## What is a paper helicopter?

When you make a paper helicopter, you’re making a propeller. Tilting the blades will enable the propeller to produce lift by creating faster moving air on the top, which has less pressure than on the bottom. If spun right, the paper helicopter will fly into the air!

## How does a paper helicopter work?

When the Roto-Copter falls, air pushes up against the blades, bending them up just a little. When air pushes upward on the slanted blade, some of that thrust becomes a sideways, or horizontal, push. … The two opposing thrusts work together to cause the toy to spin.

## How do you make a paper helicopter fall slower?

In this position, the air under one blade is pushing one way and the air under the other blade is pushing the opposite way. These two forces of air push the blades around and make it spin. The faster the blades spin, the less the air can get by, and the slower the helicopter falls.

## How do you make a paper helicopter go faster?

Try switching the direction of the folds for blades A & B. Make note of the direction the helicopter spins this time. Weight affects how quickly the helicopter spins, try adding additional paper clips and watch how the helicopter spins faster! Make the helicopters in different sizes.

## How do you make a whirlybird fall slower?

Flipping the wings causes them to spin in the opposite direction. The longer the wings, the slower the drop because of the uplift on the greater wing area.

## What factors affect the flight time of a paper helicopter?

Test factors that influence flight time must also be identified. For the helicopter experiment, the factors could be paper type, rotor length, leg length, leg width and paper clip.

## What effect does weight have on the flight time of a paper helicopter?

In doing so they create lift which helps to keep the helicopter in the air. The direction the blades are bent in will affect whether it spins clockwise or anti-clockwise. Adding more weight (paperclips) will make the helicopter fall faster.

## What force keeps helicopters up in the air?

The force that resists the movement of a helicopter through the air and is produced when lift is developed is called drag. Drag must be overcome by the engine to turn the rotor. Drag always acts parallel to the relative wind. Total drag is composed of three types of drag: profile, induced, and parasite.

## How do you make a paper helicopter out of seeds?

Make a spinning seed!

1. Cut out a strip of paper.
2. Fold the strip of paper in half.
3. Fold the top piece to the right. Flip the strip of paper over and repeat on the other side.
4. Draw a picture on each side of the paper. …
5. Attach a paper clip at the bottom end of the spinning seed, where the first fold is – this is where my legs are in the picture.

## How do you make a paper tank step by step?

Part 2 of 4: Making the Tank

1. Fold the ends of the paper into an X. Take one corner and fold diagonally to create a point. …
2. Create pointed ends. Push in the sides of the paper where you made the folds (the X at each end). …
3. Make the wheels. Fold both of the long sides of the paper once inwards towards the center.

## Why do sycamore seeds spin through the air?

Why do sycamore seeds spin? When the helicopter shaped seed falls the air pushes upwards against it. … The two arms get pushed in opposite directions, which makes the seed spin. This helps sycamore seeds to fall far from the tree so they have plenty of space to grow.

## Which falls faster book or paper?

The book’s terminal velocity is faster than the paper’s since the mass is greater. (4) The lack of a terminal velocity in vacuum and the same acceleration rate of each object as they fall. This is because the drag force goes to zero and there are no other forces to oppose acceleration.

## Does the shape of a piece of paper affect how long it takes to fall to the ground?

Due to its special shape, however, the blades will still spin as it falls. This generates additional lift that slows the whirlybird even as it drops. So, it will fall much slower than if you crumpled up the same piece of paper and dropped it.
