Resultant of two Vectors The resultant is the sum or the combined effect of two vector quantities Vectors in the same direction: 6 N 4 N = 10 N 6 m = 10 m 4 m Vectors in opposite directions: 6 m s-1 10 m s-1 = 4 m s-1 6 N 10 N = 4 N

Combining vectors When two vectors are joined tail to tail Complete the parallelogram The resultant is found by drawing the diagonal When two vectors are joined head to tail Draw the resultant vector by completing the triangle

Draw, on graph paper, a scale diagram to show this movement and calculate: The displacement at the end of the journey His average speed His average velocity An aeroplane takes off with a velocity of 110ms-1 at an angle of 25O to the horizontal runway. Calculate the horizontal and vertical components of the plane’s velocity. A coin is flicked off a table with a horizontal speed of 2ms-1. Calculate its new speed 1 second later.
