In contrast to vectors ordinary quantities that have a magnitude but not a direction are called scalars. Vectors are physical quantities that require both magnitude and direction.

Examples of vectors include displacement velocity and acceleration.
Physics examples of vectors. For example angular velocity torque angular momentum angular acceleration are axial vectors. Analytical computation of a resultant three displacement vectors a b and c in a plane figure 2 3 6 are specified by their magnitudes a 10 0 b 7 0 and c 8 0 respectively and by their respective direction angles with the horizontal direction α 35 β 110 and γ 30. Velocity is one of the most common vectors.
For example velocity forces and acceleration are represented by vectors. The national aeronautics and space website provides a complete description of scalar s and vectors along with examples and how they are used. Vector addition using and html5 applet to understand the geometrical meaning of the addition of vectors important.
Highly technical examples and explanations relating to scalar and vector quantities can be found at these internet sites. The vectors which act along the axis of rotation are called axial vectors. Each of these quantities has both a magnitude how far or how fast and a direction.
For example displacement velocity and acceleration are vector quantities while speed the magnitude of velocity time and mass are scalars. Vector direction and bearing with examples applications and questions with solutions. Pseudo or inertial vectors the vectors used to make an inertial frame of reference into the inertial frame of reference are called pseudo or inertial vectors.
When referring to the speed of an object we are not usually concerned with the direction it is travelling in. Physical concepts such as displacement velocity and acceleration are all examples of quantities that can be represented by vectors. The velocity of an object has a direction though north for example or straight up.
Interactive html 5 applets to add and subtract vectors. The greater the magnitude the longer the arrow. In physics euclidean vectors are used to represent physical quantities that have both magnitude and direction but are not located at a specific place in contrast to scalars which have no direction.
Each of these quantities are unique in that a full description of the quantity demands that both a magnitude and a direction are listed. Free sat ii physics practice questions vectors with detailed solutions and explanations. It is very similar to speed except it has a direction.
Examples of vector quantities that have been previously discussed include displacement velocity acceleration and force. Examples of scalars include height mass area and volume.
