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.
Impulse & Momentum. Summary. 1  is a quantity that describes an object's resistance to stopping (a kind of moving inertia). 2  is represented by the symbol p (boldface). 3  is the product of an object's mass and velocity.  is a vector quantity (since velocity is a vector and mass is a scalar).
