# Energy bar charts chemistry

Kinetic energy is 0.5*mass*(velocity)^2. If you know the object is in free fall then you know the only force acting on it is g and a resistive force so you can work out how v evolves with time and hence kinetic energy.Standard Thermodynamic Values at 25°C Please note that enthalpy and free energy values are given in kJ/mol while entropy values are given in J/(mol·K).
