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.
The product of average force and the time it is exerted is called the impulse of force. From Newton's second law. the impulse of force can be extracted and found to be equal to the change in momentum of an object provided the mass is constant:f an impact stops a moving object, then the change in momentum is a fixed quantity, and extending the time of the collision will decrease the impact force by the same factor. This principle is applied in many common-sense situations:
