# What is the definition of position in physics?

In

**physics**,**position is**usually a number on an axis. A number where direction doesn't matter**is**called a scalar.**Position is**a vector, because direction matters. But distance**is**a scalar. Distance**is**how far you've traveled.A.

### What is the definition of direction in science?

**Direction**is defined as the path that something takes, the path that must be taken to reach a specific place, the way in which something is starting to develop or the way you are facing. An example of

**direction**is when you go right instead of left.

#### Where is East West North South?

The four cardinal directions or cardinal points are the directions**north**,**east**,**south**, and**west**, commonly denoted by their initials N, E, S, and W.**East**and**west**are at right angles to**north**and**south**, with**east**being in the clockwise direction of rotation from**north**and**west**being directly opposite**east**.#### How can I know direction?

**These cardinal directions can be abbreviated as N, S, E, and W.**- Cardinal points: north, south, east, and west.
- The sun rises in the east and sets in the west.
- To understand where north, south, east, and west are, first point your left arm towards the sun in the morning.

#### What is the definition of position in science?

A Definition of**Position**. Your browser does not support iframes. Not Required Viewing. An object's**position**is its location relative to a reference point (or origin of a coordinate system).**Position**is a vector quantity because it does have a direction.

### What is direction in vectors?

The

**direction**of a**vector**is often expressed as an angle of rotation of the**vector**about its "tail" from east, west, north, or south.#### What is the direction vector?

A**vector**contains two types of information: a magnitude and a**direction**. The magnitude is the length of the**vector**while the**direction**tells us which way the**vector**points.**Vector direction**can be given in various forms, but is most commonly denoted in degrees. Acceleration and velocity are examples of**vectors**.#### How do you find the direction of a vector?

**Sample question**- Apply the Pythagorean theorem to find the magnitude. Plug in the numbers to get 5.1.
- Apply the equation theta= tan
^{–}^{1}(y/x) to find the angle. Plug in the numbers to get tan^{–}^{1}(5.0/1.0) = 79 degrees.

#### What is an example of a vector?

**Examples**of such**quantities**include distance, displacement, speed, velocity, acceleration, force, mass, momentum, energy, work, power, etc. All these**quantities**can by divided into two categories -**vectors**and scalars. A**vector quantity**is a**quantity**that is fully described by both magnitude and direction.

C.

### What is the definition of magnitude in physics?

In

**physics**, speed is a pure scalar, or something with a**magnitude**but no direction --such as 5 m/s. 5 meters per second does not tell us which way the object is moving. It gives us no clue about the direction. On the other hand, velocity, in**Physics**, must be expressed as a vector with both a**magnitude**and a direction.#### What is the meaning of magnitude in science?

The**magnitude**is a number that characterizes the relative size of an earthquake.**Magnitude**is based on measurement of the maximum motion recorded by a seismograph.#### What is a scalar quantity?

A**scalar quantity**is a one dimensional measurement of a**quantity**, like temperature, or mass. A vector has more than one number associated with it. A simple example is velocity. It has a magnitude, called speed, as well as a direction, like North or Southwest or 10 degrees west of North.#### How do you find the magnitude of a force?

**Find the magnitude of force acting upon a cart weighing 100 N and accelerating at the rate of 2.5 m/s**^{2}.- Remember, 10 N is equal to 9.8 kg. So, convert Newtons to kg by dividing by 9.8 kg. Your new kg value should be 10.2 kg for the mass.
- Multiply your new mass value (10.2 kg) times the acceleration (2.5 m/s
^{2}).
