Speed is a scalar quantity that refers on how fast and object is moving, speed can be thought of as the rate at which and object covers distance. An object with no movement at all has a zero speed.
Cant be velocity because it has to include distance for example "80 miles toward east"
acceleration is almost as velocity just includes going faster or slower or turning.
I believe the sunbird would benefit the plant because it would pollinate them. Going from flower to flower, pollen would get stuck on it's feathers and it would pollinate other flowers, like a bee.
