What determines an objects velocity

Speed and Direction determines an objects' velocity. And that's why the formula for velocity is similar to speed.

The formula is that you have to divide the distance by the time it takes you to travel that same exact distance, then you have to add your direction.

But if you're talking about what determines an objects Terminal velocity, then, gravity and drag determines it because gravity speeds the object up while drag (which is caused by friction) slows it down. And when these two forces are applied to an object, the certain object is said ti have reached it Terminal velocity.

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
