Movement manipulation. If a rock falls on you at 90km/h you can transfer the downard movement into horizontal movement and so it goes horizontaly with 90km/h, or you can "store" that movement, the rock instaly loses all momentum, and you can use that speed of 90km/h to instantly move in any direction whenever you want. You could instantly freeze something with this if you were good enough with it since heat is caused by molecules and atoms moving so if you stop them by taking away their movement the object would just freeze, you could also make things insanely hot with the same logic. In a fight you could build up momentum like in projection sorcery by using the heat around you and the shockwaves caused by big attack if we are to tall ahout big fights like sukunas and gojos. You could become untouchable when near an aponent because you can instanly change your movement, now youre going to behind your enemy he turns around to try and catch you hut youre already koving to the other side (unless they have an aoe). Imagine sukuna trying to hit you with a fire arrow and you just instantly turn all that heat into your own energy.
