You are familiar with one-dimensional kinematics. now you will use your prior knowledge to analyze a situation involving two-dimensional motion. the video shows a "free-falling disk" in slow motion, with a superimposed grid and a frame counter that would allow you to make distance and time measurements right off the screen, without using any additional measuring equipment. by using the experimental data, you will discover the patterns in the motion of the disk and will be able to describe that motion quantitatively.

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.
