The momentum is a physical magnitude that measures the product of the object's velocity by its mass. The total momentum of a system is the sum of all its components' individual momentums. The two-bear system starts with a total moment of
When both bears stick together, the total mass is 20 kg, and the new momentum is
We have assumed both bears move to the right after the collision. In this situation, the total momentum is conserved
Soap breaks up the oil into smaller drops, which can mix with the water. It works because soap is made up of molecules with two very different ends (one end of molecules are hydrophilic, so they love water; the other end of molecules is hydrophobic, so they hate water).
Kinetic energy is a result of mass in motion at a certain velocity. <span>1 Joule = 1 kg • (m/s)<span>2 </span></span>the force as a function of mass of the object.
<span>The factors that influence wind and contribute to global winds are pressure gradient, Rossby waves and jet streams, and local weather conditions.</span>
