2.5 Resolving Vectors

Question 1

Define a resultant vector

Answer 1

A single vector which has the same effect as 2 or more vectors added together

Question 2

State Pythagoras’ theorem

Answer 2

a^2 + b^2 = c^2 the square length of the hypotenuse equals the sum of the squares of the lengths of the 2 other sides

Question 3

A component of a vector is…

Answer 3

1 of the 2 perpendicular vectors obtained by resolving a vector

Question 4

State the equation used to resolve vectors of both of their components

Answer 4

Vector 1 = Fx = fcostheta
Vector 2 = Fy = fsintheta
