As the bike accelerates from rest, it gains Fill in the blank text field 1 Type here. energy. Some of this energy is converted into thermal energy due to wind resistance, a form of Fill in the blank text field 2 Type here. . When the bike flies through the air on a jump, the wheels no longer propel the bike forward. Instead, the motion of the bike is governed only by the force of Fill in the blank text field 3 Type here. . When the bike lands, it no longer has any gravitational Fill in the blank text field 4 Type here. energy because its displacement from the ground is zero.
