Vectors, Components & Trigonometry — Drills · Grade 12 Science
Chapter: Measurement & Vector FoundationsWhat these drills covers
By the end of Vectors, Components & Trigonometry you should be able to:
- I can resolve a vector into signed components and add vectors.
- I can recover resultant magnitude and direction with quadrant checks.
2 questions, numeric and written answer, each with a worked explanation.
Vocabulary used: scalar, vector, component.
Problem 1
Find resultant magnitude of 6N east and 8N north.
Hints
Write the relationship first; substitute with consistent units.
Answer and explanation
10 N
√(36+64)=10.
Problem 2
Two 12N opposite horizontal forces act. Find net force.
Answer and explanation
0N; opposite signed components cancel.
Response criteria
- State a scientifically accurate conclusion.
- Show the calculation or mechanism that supports it.
- Include units, conditions, or limits where relevant.
