to say the truth, longer ones are better, because of the bernoulli principle.
I have also had an assighment on this just a day ago and we tried it in my grade 7 class. Good luck
Within reason they do. Designers make a blade of optimum length and chord.
Wing length doesn't directly affect helicopter flight because helicopters use rotor blades to generate lift, not wings. The length of rotor blades on a helicopter can impact its performance by affecting lift, control, and stability. In general, longer rotor blades can provide more lift and stability, but may also require more power to rotate.
To improve the hang time of a paper helicopter, you can try adjusting the weight distribution by adding paper clips to the body to help it float longer. Additionally, trimming the blades to ensure they are balanced and have a larger surface area can also increase the hang time. Finally, experimenting with different folding techniques and angles of the blades may also help optimize the helicopter's performance.
Large fan blades have more mass and therefore more inertia, which allows them to keep rotating for a longer time before friction and air resistance slow them down. On the other hand, shorter blades have less mass and less inertia, causing them to stop rotating more quickly.
shorter recess is better because you will learn more in school because there will be more learning time.
Hair clipper blades come in various sizes, typically ranging from 000 (1/50 inch) to 8 (1 inch). The size of the blade affects the length of the hair that is cut, with smaller blades cutting shorter lengths and larger blades cutting longer lengths. Different blade sizes can also impact the precision of the cut and the overall style outcome, with smaller blades providing more detailed and intricate cuts, while larger blades are better suited for longer, more uniform cuts.
A longer arm makes more velocity, longer distance, and more height
The shape of the blade of a paper helicopter can affect its flight by influencing factors such as lift and drag. Blades with a larger surface area or more angled design may generate more lift, while blades with a streamlined shape may reduce drag, resulting in longer flight times. Experimenting with different blade shapes can help optimize the performance of a paper helicopter.
Planes are much easier to control and so will last longer.
Mopeds are generally better for longer travel then scooters made for shorter traveling.
The length of the rotor blades will affect the paper spinner's flight by influencing the lift generated. Longer blades can produce more lift due to a larger surface area, allowing the spinner to stay in the air for longer periods. Shorter blades may not generate enough lift, causing the spinner to fall more quickly.
Speed Skating. This is the events where they race around the ice track, and they have longer blades for smoother skating, better traction and more speed.
