Question

vectors quick check
which quantity is scalar? (1 point)
○ velocity
○ force
○ energy
○ momentum

Explanation:

Scalar quantities have only magnitude, while vector quantities have both magnitude and direction. Velocity, force, and momentum are vectors (they have direction). Energy has only magnitude (e.g., kinetic energy \( KE = \frac{1}{2}mv^2 \) depends on speed's magnitude, not direction), so it's a scalar.

Answer:

C. energy
