What to Focus On
- Scalar: only magnitude (e.g., mass, speed)
- Vector: both magnitude and direction (e.g., velocity, force)
- Vectors are represented with arrows
- Use triangle or parallelogram law for vector addition
- Vector addition is commutative: A + B = B + A
- Vector addition is associative: A + (B + C) = (A + B) + C
- Scalar multiplication: kA has magnitude |k|A, direction same (k>0) or opposite (k<0)
- Dot product: A·B = AB cosθ — scalar result
- Cross product: A×B = AB sinθ — vector result, perpendicular to A and B
Common Mistakes to Avoid
The path of a projectile is parabolic only when air resistance is present.
Centripetal force is a new kind of force that appears in circular motion.
At the highest point of a projectile, the velocity is zero.
Memory Tips
Difference between scalar and vector quantities
Triangle Law of Vector Addition
Parallelogram Law of Vector Addition
Vector Subtraction: A - B = A + (-B)
