Explanation:
Speed of sound: solids > liquids > gases. In steel ~5000 m/s, water ~1500 m/s, air ~340 m/s. Vacuum no propagation. Speed depends on density and elasticity.
Explanation:
Speed has magnitude only, scalar. Velocity is vector (speed + direction). Momentum and force are vectors. Distance is scalar, displacement vector.
