Examine the setup in front of you. you have gliders that are free to move on air tracks. you have two photogates that can be used to measure the speed of a glider that passes through the photogate. the photogate measures the time that elapses while a glider passes through. how can you determine the speed of the glider from the photogate measurement

d. learned preferences i believe is your answer

b

explanation:

bc its just b

the answer would be a

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.
