A skydiver experiences two forces when in freefall. One is gravity, which he has no control over. The other is air resistance, a type of fluid friction. By changing the position of his dive relative to his direction, a skydiver can fall faster or slower, spin, etc. By spreading his limbs out and assuming a laying position in the air he would produce the most air resistance and slow his descent. At some point, however, the parachute (also causing air resistance) would be deployed and slow him further.
A skydiver can use friction by adjusting the position of their body to increase surface area and create more drag. By spreading out their limbs, the skydiver can encounter more air resistance, which helps to slow down their descent speed. This increase in friction allows the skydiver to control their rate of descent and eventually deploy their parachute safely.

Friction is both friend and foe?
Friction can be considered a friend because it allows us to walk, drive cars, and hold objects. It provides the necessary grip and traction for various activities. However, friction can also be seen as a foe because it can slow us down, cause wear and tear on machinery, and reduce energy efficiency.
What three ways can friction be useful?
Friction allows us to walk without slipping by providing grip between our feet and the ground. It helps to slow down moving objects, such as vehicles coming to a stop on a road. Friction is essential for writing with a pencil, as it allows the graphite to leave marks on paper.
What way is friction helpful?
Friction is helpful because it allows us to walk, hold objects, and drive vehicles by providing the necessary grip or traction. It also helps to slow down moving objects and prevent them from sliding or slipping. Additionally, friction plays a crucial role in many mechanical systems by helping to transfer force and transmit power.
Why is friction sometimes necessary?
Friction is necessary in many situations to provide traction, allowing us to walk, drive, or grip objects. It is also important for braking systems, as it helps slow down moving objects by converting kinetic energy into heat. In some cases, controlled friction is necessary for tasks like writing with a pen or playing musical instruments.
What is the magnitude of the force of gravity on the skydiver with 845 N?
If you're telling us that the skydiver weighs 845 newtons, then that's the magnitudeof the forces of gravity between him and the Earth whenever he's near the Earth.
How does friction helps us move from place to place?
it slow s us down so we dont too fast past where we want to go.

Is friction a friend or a foe?
Friction can be both a friend and a foe. It allows us to walk, hold things, and even write due to the grip it provides. However, friction also causes wear and tear in machinery and can slow down motion, which may not always be desirable.
How does friction help us move from place to place?
Friction provides the necessary grip between our feet and the ground to push off and propel ourselves forward when walking or running. It helps us maintain stability and control while moving by increasing traction and reducing slipping. Without friction, it would be very difficult to generate the necessary forces for efficient movement.
What are two ways that friction can be useful?
These came of of the top of my head so here it is it can be used to produce heat or to slow things down in the air. Hope this helped:)
How does braking stop a bicycle?
Same as on a car. Applying the brakes means that something stationary is pressed against a moving part. This generates friction, which turns speed into heat.It produces friction, because when the brake touches the rim of the bicycle, the bicycle slows down. (thats called friction) And after a while the bicycle stopsA stationary part is brought into contact with a rotating part. The resulting friction slows the bike down.
Describe 3 examples where friction is useful?
Walking is an example of friction. when friction is formed you may slow down, but you may have a weak balance and fall to your height. friction can be used in many places, like themeparks and ice skating and even on the sole of your shoes.
