Question

0.80 kilogram bird is flying at a constant speed of 5.0 m/s and is 6 m above the
ground. What is the bird's potential energy?​

Answer 1

Answer:

☆Concept:

》whenever anything is at height from earth's surface it has some potential energy (U).

》it doesn't matter in which way its moving it will have some potential energy.

so whatever speed its moving doesn't effect its U.

☆Formula:

$\boxed{\bf{\red{ PE = mgh}}}$

where m=mass of object,g=gravity,h=height from the ground.

☆Solution:

▪︎m=0.8kg

▪︎g=10m$\ s^{-2}$

▪︎h=6m

》PE = mgh

》U = 0.8×10×6

》U = 48J

☆☆bird's PE is 48J
