If P is the momentum of an object of mass m, then the expression P2/m has the same unit as?
Answer: Energy
Explanation
Momentum (p) is defined as mass (m) multiplied by velocity (v), so p = mv.
If we square p and divide by m, we get: p^2/m = (mv)^2/m = mv^2.
This is the formula for kinetic energy.
Therefore, p^2/m has the same unit as energy.
