Topic 3: Uniform Motion & Velocity

Question 1

scalar quantities

Answer 1

describes magnitude (size/amount) of motion (student lives 5km from school)

Question 2

vector quantities

Answer 2

describes magnitude & direction of motion (lives 5km south of school)

Question 3

cartesian method

Answer 3

right x axis is the start, angle of 0
angles increase when moving counter clockwise

Question 4

navigator method

Answer 4

north is start, angle of 0
angles increase when moving clockwise

Question 5

speed

Answer 5

scalar quantity, related to distance over time (ex. km/h)

Question 6

velocity

Answer 6

vector quantity, related to object’s displacement over time (ex. km/h [N])

Question 7

distance

Answer 7

scalar quantity, length between 2 points

Question 8

displacement

Answer 8

vector quantity, straight line distance between 2 points, includes direction
displacement = end position - start position (m)

Question 9

position

Answer 9

vector quantity, specific point relative to reference point
