Suppose a tornado suddenly occurred outside your front door which is 180 cm high and 97 cm wide What net force would be exerted on the door?
In order to calculate the force we would net to know the wind speed of the tornado. The door has an area of 1.746 square meters To calculate the pressure load first find the pressure by squaring the wind speed (in mph) and multiply it by 0.123 to get the pressure in pascals, and then multiply by the surface area and the drag coefficient (which in this case is 2.0 for a flat surface). To give a good range, EF0 tornado winds start at 65 mph. Such a wind would exert a force of approximately 1,800 newtons (400 pounds). The highest winds ever recorded in a tornado were 302 mph. Such a wind would exert about 39,000 newtons (8,800 pounds) of force.
What is the significance of the inverse-square law?
Its the earth, wind and the fire
Does wind move in a straight line?
No. It is affected by localised pressure differences, thermals - which depend on the the heat-retention property of the surface, surface contours (including man-made ones).
What is the variables of throwing?
wind and its direction amount of force applied may differ each throw aiming skills
How do kites stay up in the air?
Kites stay in the air because of the force exerted on them by moving air (wind). If there were no wind then the kite would fall to the ground. This is because gravity is always trying to pull the kite down. Now the force of wind comes in to play to keep the kite in the air. The kite is at an angle to the ground, and it looks like this slash when it is flying in the air ---> / That is important because as the kite catches the wind two orthogonal forces are applied to the kite. One that is anti-parallel to gravity (Meaning the force is pointing up.) and one that is orthogonal to gravity. We don't necessarily care about the orthogonal force for our example so let's forget about it. The force generated on the kite that is anti-parallel to gravity is what keeps it in the air, so long as the anti-parallel force is greater than the weight of the kite.
