4 cards from this section. Quick, good the night before a test.
If vector A is represented as 4i + 2j, what is 3A?
Multiply each component by the scalar.
What happens to the vector if you multiply it by 0?
Consider what the magnitude becomes.
What happens to the direction of a vector when multiplied by a negative scalar?
Think about how a negative sign affects movement.
If A = 1i + 1j, what is the result of multiplying A by 5?
Scale the components by 5.
Given a vector A = 4i + 2j and k = -3, calculate the resulting vector after performing scalar multiplication. What does this tell us about the vector's direction?
Multiply each component by the scalar.
In a physics context, if a force vector F = 10i + 5j is scaled by 0.5, what is the new force vector? Explain its significance.
Think about how halving the force affects movement or acceleration.
