Are all forces vectors? What forces do and don't conserve energy? What is the English unit of force? Its one of those little web search things, and some of those aren't so easy to find...
A vector is a mathematical object that has both magnitude (size) and direction. It is represented by an arrow, with the length of the arrow representing the magnitude and the direction of the arrow representing the direction.
A scalar is a mathematical object that only has magnitude (size) and no direction. Examples of scalars include temperature, speed, and mass. Vectors, on the other hand, have both magnitude and direction, and examples include force, velocity, and displacement.
Yes, all forces are considered vectors because they have both magnitude and direction. In order to fully describe a force, we need to know its strength (magnitude) and the direction in which it acts.
Yes, a vector can have a negative magnitude. This indicates that the vector is acting in the opposite direction of its original orientation. For example, a force of -10 Newtons would mean that the force is acting in the opposite direction of the original force of 10 Newtons.
A vector is typically represented by an arrow, with the length of the arrow representing the magnitude and the direction of the arrow representing the direction. Vectors can also be represented mathematically using coordinates or components, such as (x, y) or
