Parallelogram Of Forces/ Vectors Apparatus For Physics

Objective: Our objective is to find the weight of a given body using the Parallelogram Law of Vectors. TheoryWhat does the Parallelogram Law of Vectors state? 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. Parallelogram Law of Vectors explained Let two vectors P and Q act simultaneously on a particle O at an angle . 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. 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, or 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 the other two hangers then, Now construct a parallelogram OACB by assuming a scale (say 1cm=50 gwt) corresponding to the weights P and Q. The diagonal of the parallelogram OC will give the resultant vector. The weight of the unknown body, If W is the actual weight of the body, then the percentage error in the experiment can be calculated using the equation, Learning Outcomes: Students learn what is parallelogram law of vectors. They become familiar with the Gravesands apparatus. Students are able to find the unknown weight of an object using the parallelogram law of vectors. Materials Required: Parallelogram Law of Forces apparatus (Gravesand’s apparatus) Plumb line Two hangers with slotted weights A body (a wooden block) whose weight is to be determined Thin strong thread White drawing paper sheet Drawing pins Mirror strip Sharp pencil Half meter scale Set squares Protractor

Labappara Newton's Law For Physics

Newton's First law of Motion: Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. It may be seen as a statement about inertia, that objects will remain in their state of motion unless a force acts to change the motion. Newton's Second law of Motion: The unit is based on a substantial metal casting and the entire mechanism is visible. The spring gun offers two tensions. The 25 cm long unit has a 10 mm rod. It may be horizontally clamped to a support stand or table clamp. Complete with two steel balls. Newton's Third law of Motion: To every action there is an equal and opposite reaction.
