KE = 1/2 * m * v²
where:
* KE is kinetic energy
* m is mass
* v is velocity
However, there are situations where you can indirectly find the kinetic energy without directly using velocity:
1. Using momentum and mass:
* Momentum (p) = mass (m) * velocity (v)
* KE = p²/2m
If you know the momentum and mass, you can calculate kinetic energy using this formula.
2. Using work-energy theorem:
* Work (W) = Change in Kinetic Energy (ΔKE)
* KE₂ - KE₁ = W
If you know the work done on an object and its initial kinetic energy, you can find its final kinetic energy.
3. Using conservation of energy:
* Total energy (E) = KE + PE
* E₁ = E₂
If you know the initial potential energy and the total energy, you can find the kinetic energy.
In essence, you need to find a way to relate kinetic energy to other known quantities that don't directly involve velocity.
