VECTORS, SCALARS, AND COORDINATE SYSTEMS 4. A student writes, “A bird that is diving for prey has a speed of -10 m/s ” What is wrong with the
student's statement? What has the student actually described? Explain.
5. What is the speed of the bird in Q4?

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
