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 are the comparative and superlative of useful?
more useful, most useful
What is the Comparitive and superlative of useful?
more useful and 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 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.
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
List some low friction and not useful?
Ice on a flat surface - low friction but not useful for walking safely Greasy surfaces - low friction but not useful for handling objects securely Wet banana peel - low friction but not useful for maintaining balance
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.
