What is Vector physics – definition, examples, and notation.Vectors can be denoted in several ways in text, a few are shown in the figure below: The length of the line represents the magnitude of the vector and the direction of the arrowhead indicates the direction of the vector. A vector can be graphically represented by a line with an arrowhead. Let’s take an example: The quantity 55 km per hour is a scalar, while the quantity 55 km per hour to the east is a vector. What is vector physics? Vectors in physics are physical quantities that not only have magnitude but also direction. What is Vector physics – definition, examples, and notation Examples of vector quantity are displacement, force, torque, velocity, acceleration, momentum, and electric current. Vector Definition : Vectors in physics are physical quantities that have magnitude as well as direction. Examples of scalars are length, speed, mass, density, energy, power, temperature, charge, and potential difference. Scalar Definition: Scalars are physical quantities that have a magnitude only. The physical quantities measured in physics can be divided into two groups, scalars, and vectors. The quantity which can be measured is called physical quantity. To understand it we have to proceed step by step starting with physical quantity. Students are able to find the unknown weight of an object using the parallelogram law of vectors.Vector physics is one of the most fundamental chapters in high school physics where we learn about Vector and Scalar quantities.They become familiar with the Gravesands apparatus.Students learn what is parallelogram law of vectors.If W is the actual weight of the body, then the percentage error in the experiment can be calculated using the equation, The diagonal of the parallelogram OC will give the resultant vector. Now construct a parallelogram OACB by assuming a scale (say 1cm=50 gwt) corresponding to the weights P and Q. P and Q are suspended from the other two hangers then, On a Gravesand's apparatus, if the body of unknown weight (say S) is suspended from the middle hanger and balancing weights The unknown weight can be calculated from the equation (1). On a Gravesand's apparatus, if the body of unknown weight (say S) is suspended from the middle hanger and balancing weights P and Q are suspended from othe two hangers then, They are represented in magnitude and direction by the adjacent sides OA and OB of a parallelogram OACB drawn from a point O.Then the diagonal OC passing through O, will represent the resultant R in magnitude and direction. Let two vectors P and Q act simultaneously on a particle O at an angle. If two vectors acting simultaneously on a particle are represented in magnitude and direction by the two adjacent sides of a parallelogram drawn from a point, then their resultant is completely represented in magnitude and direction by the diagonal of that parallelogram drawn from that point. Theory What does the Parallelogram Law of Vectors state? Our objective is to find the weight of a given body using the Parallelogram Law of Vectors.
