vectors and scalars

Question 1

Vector quantities

Answer 1

Have size (magnitude) and direction 
Force, Velocity, Displacement, acceleration, momentum

Question 2

scalar quantities

Answer 2

Only have size (magnitude)

Mass, Speed, Distance, Time, Current

Question 3

Newtons second law

Answer 3

F = ma
Force = mass times acceleration

Question 4

Parallelogram method of vector addition

Answer 4

two vectors acting at a point are drawn as the adjacent sides of a parallelogram, their resultant is represented by the diagonal drawn from that point

Question 5

Head to tail method of vector addition

Answer 5

Scale diagram, add head of 1st vector on to the tail of the next vector, resultant from start to finish point
