What else can I help you with?
What would the force of a skydiver with a mass of 70 kg and accelerates at 9.8 ms2 be?
The force is 686 newtons. (Force = mass x acceleration).
What is the Superlative and comparative to the word useful?
Most useful and more useful.
Why is it useful to rewrite a formula in terms of another variable?
to be more clear and not mix up your work. i suggest this all the way.
What is the Comparitive and superlative of useful?
more useful and most useful
What are the comparative and superlative of useful?
more useful, most useful
What are 2 way in which friction can be useful?
Brakes, and Shoes
Is one way that friction is useful?
stopping cars Friction is useful to start a fire with sticks.
How can a skier achieve greater velocity than a skydiver?
If a skier is in a jump, then a skier and skydiver is pretty much the same thing. In general though, a skydiver has only air resistance, the skier has air resistance and friction with the ski-snow, so the skydiver has an edge on speed.
What friction causes a sky divers to change as she falls?
As a skydiver falls, air resistance causes friction against her body, gradually slowing her down. This friction increases as her speed decreases, ultimately leading to a terminal velocity where the forces of gravity and air resistance balance, resulting in a constant falling speed. This friction also helps stabilize the skydiver's position during free fall.
How does a skydiver us friction to slow down?
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.
Does brakes on a bicycle have a lot of friction or not much and is it useful or not useful?
Brakes are meant to have a lot of friction and it's useful.
What is an example of air friction?
An example of air friction is when an object moving through the air experiences resistance due to the interaction between its surface and the air molecules. This resistance slows down the object's motion, such as when a skydiver experiences air resistance while falling through the atmosphere.
Is friction useful with computers?
No Friction Runes Computers
When can friction not be useful in a boat?
the friction from pushing the hull through the water is not useful as long as you're travelling.
When is a high friction useful?
It can be useful when a ball is catching
As a skydiver fallsthe air is forced around him.what energy transformation doe's this cause?
As the skydiver falls, the air resistance forces kinetic energy to be transformed into thermal energy due to friction between the air and the skydiver's body. This reduces the speed of the skydiver as they fall towards the ground.
Why are tyres useful friction?
how does friction help car tyres?
