Escape velocity is the minimum velocity needed to escape. The minimum velocity results in zero kinetic energy at infinity. Since kinetic energy is based on motion, it is always a positive value. If it is not in motion, the kinetic energy of that object is zero. Kinetic energy can never be a negative value. Kinetic energy can be quantified as one half of the mass times the velocity squared (KE = 1/2*m*v²). To have something at absolute zero in theory means it has no kinetic energy, but that's not possible, because then the materials would cease to exist as normal matter, due to laws of quantum mechanics. Because mass can't be negative and the square of speed gives a non-negative number, kinetic energy can't be negative. Either something is moving and has positive kinetic energy, or it is not moving and has zero kinetic energy. Kinetic energy must always be either zero or a positive value. While velocity can have a positive or negative value, velocity squared is always positive. Kinetic energy is not a vector.

Absolute zero is where the kinetic energy of the particles is zero. That means all the motion between particles will cease. At Absolute Zero temperature (−273.15°C), all the molecules are expected to have no kinetic energy and hence no molecular motion. All molecular motion ceases if the temperature is reduced to absolute zero, hence kinetic energy will be equal to zero at 0 kelvin. Zero kelvin is the lowest possible temperature. At absolute zero, all motion comes to a standstill. It is obvious that a lower temperature is not feasible because there is no velocity smaller than zero and no energy content less than nothing. Nothing in the universe or in a lab has ever reached absolute zero as far as we know. Even space has a background temperature of 2.7 kelvins. At very low temperatures in the vicinity of absolute zero, matter exhibits many unusual properties, including superconductivity, superfluidity, and Bose–Einstein condensation. Kinetic energy must always be either zero or a positive value. While velocity can have a positive or negative value, velocity squared is always positive. Kinetic energy is not a vector. Since kinetic energy is based on motion, it is always a positive value. If it is not in motion, the kinetic energy of that object is zero. Kinetic energy can never be a negative value. Kinetic energy can only be zero or positive; it can never be negative. This is because kinetic energy is defined as half an object's mass multiplied by the object's velocity squared. Mass can never be negative because it is a measure of matter, and velocity is always positive because it is squared.
