It is tornado that is formed over a water body, usually an ocean or sea.They are similar to the mesocyclonic thunderstorm tornadoes but are formed over a water body. A waterspout is not a destructive tornado as it spans itself over less than 2 km. Tornadoes of these type cause damage that tends to be EF2 or less.
The impulse of force is commonly used to calculate forces in collisions. Active formula Impulse = Average force x time = mass x change in velocity. Enter data below and then click on the desired quantity in the active formula above.
When you apply a force for a certain amount of time, you create an impulse. In fact, that's the definition of impulse â impulse equals the force applied multiplied by the time it was applied. Here's the equation: Note that this is a vector equation because the force has a direction; therefore the impulse does as well.
