Where is the gravitational potential energy?

Click For Summary
SUMMARY

The discussion centers on the concept of gravitational potential energy (PE) in relation to kinetic energy (KE) of a projectile immediately after it exits a gun. Participants emphasize the importance of considering gravitational PE when calculating KE at various points in the projectile's trajectory. It is noted that while the small change in height during the projectile's travel through the gun is often ignored, it still plays a role in the overall energy calculations. Understanding these energy transformations is crucial for accurate physics problem-solving.

PREREQUISITES
  • Understanding of gravitational potential energy (PE)
  • Knowledge of kinetic energy (KE) principles
  • Familiarity with projectile motion concepts
  • Basic grasp of energy conservation laws
NEXT STEPS
  • Study the relationship between gravitational potential energy and kinetic energy in projectile motion
  • Learn about energy conservation in closed systems
  • Explore the effects of height on gravitational potential energy calculations
  • Investigate the role of initial velocity in projectile trajectories
USEFUL FOR

Physics students, educators, and anyone interested in understanding the principles of energy transformation in projectile motion.

Note that they are talking about the KE of the projectile immediately after it leaves the gun. You still need to consider gravitational PE if you want to find the KE at other points. (They are ignoring the small change in height of the projectile as it travels through the gun.)
 
ok. thank you very much. I was accounting for the small change in height
