• an arrow moves forward when released from a stretched bow.explain the transformation of energy in the process.
• forelimbs of birds are modified.give reasons.

please answer fast.tommorow i have an exam

• When the bow is streched, potential energy is filled into the bow. When the arrow is allowed to go, all this energy converts into kinetic energy.
• Birds have developed the ability of flying. So their forelimbs are in the form of wings.

thanks for wishing but dont you think we have to explain both of them//

1.potential energy to kinetic energy

2.because the main mode of locomotion used by most of the bird species is flight

plz thumb up aisha
