The velocity of the object is similar to speed but has one main difference: velocity takes into account the direction of an object. Since speed does not take direction into consideration, it is considered to be a scalar quantity. Thus, the speed of an object can never be negative.
A) the water particles must have lost energy. As things get warmer, the particles have more kinetic energy and begin to move faster.
They are among the only types of organisms that get their energy from a non-living thing, and they give energy to Primary consumers, which give energy to secondary consumers, which give energy to tertiary consumers, which can give energy to decomposers, etc.
A gene is a hereditary trait in your body and also apart of your DNA not visible to the naked eye making up how you look
The kinetic energy of an object depends on both its mass and its speed. Kinetic energy increased as mass and speed are increased.
