Vector multiplication of two vectors yields a vector product, with the magnitude equal to the product of the individual vectors multiplied by the sine of …
To define some physical quantities, there is a need to specify both magnitude as well as direction. For example, when the U.S. Coast Guard dispatches a …
Scientists typically make repeated measurements of a quantity to ensure the quality of their findings and to evaluate both the precision and the accuracy …
Scientists always try their best to record measurements with the utmost accuracy and precision. However, sometimes errors do occur. These errors can be …
The position of an object defines its location relative to a convenient frame of reference at any particular time. A frame of reference is an arbitrary …
To describe the motion of an object, one should first be able to describe its position (where it is at any particular time). More precisely, the position …
Newton's second law is closely related to his first law of motion. It mathematically gives the cause-and-effect relationship between force and changes …
In the years before Newton, a general belief prevailed that different laws governed objects in the sky than objects on Earth. When Kepler wrote down the …
Light interacts with an organism’s integument on a variety of spatial scales. For example in an iridescent bird: nano-scale structures produce color; the …
Multi-dimensional and transient flows play a key role in many areas of science, engineering, and health sciences but are often not well understood. The …
A technique to measure the temperature of water and non-turbid aqueous media surrounding an induction-heated small magnetic sphere is presented. This …
