Video: Fossil: Definition, Types, Characteristics & Examples. Fossils provide scientists with many clues about Earth's history, offering evidence of dinosaurs and strange plants that existed in the past. This lesson will define a fossil, look at different types and characteristics of fossils, and then describe how fossils are formed.
The final result of the dot product process can be: 1  Zero: we don't have any growth in the original direction. 2  Positive number: we have some growth in the original direction. 3  Negative number: we have negative (reverse) growth in the original direction.
The âDotâProduct (Vector Multiplication) Multiplying 2 vectors sometimes gives you a SCALAR quantity which we call the SCALAR DOT PRODUCT. In polar notation consider 2 vectors: Î¸ 1 & Î¸ 2 The dot product between A and B produces a SCALAR quantity. The magnitude of the scalar product is defined as: Where Î¸Î¸Î¸Î¸ is the NET angle between the two vectors. As shown in the figure.
