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.
In general, elastic collisions are characterized by a large velocity change, a large momentum change, a large impulse, and a large force. Use the impulse-momentum change principle to fill in the blanks in the following rows of the table. As you do, keep these three major truths in mind: The impulse experienced by an object is the forceâ¢time. The momentum change of an object is the massâ¢velocity change. The impulse equals the momentum change. Click the button to view answers.
