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 is the change in momentum of an object, and is a vector quantity: j = Î´ p. Momentum is the product of the mass and the velocity of an object, and is a vector quantity: p = m v. Since in daily life we do not notice an object's mass change just because its velocity changes, change in momentum is given by:
