Vector test Questions And Answers define vector and give an example - correct answer magnitude and direction, velocity
define scalar and give an example - correct answer magnitude only, time
Why do non-perpendicular vectors need to be resolved into components before adding? - correct answer it doesnt make a right triangle and the pythagorean theorem and tangent functions can only be applied to right triangles
define resultant - correct answer sum of all vectors
define equilibrant - correct answer opposite of resultant
Why do you resolve a vector into x and y components? - correct answer you have to factor in the vertical and horizontal displacements
why do we use the pythagorean theorem - correct answer to find the resultant and equilibrant
a football player runs directly down the field for 35 m before turning to the right at an angle of 45 degrees and then ran 15 m. What is his magnitude and direction? - correct answer 46.8m 12.6 degrees right
