SUMMARY

In both a vacuum and real-world conditions, a projectile dropped from rest and one shot horizontally from the same height will hit the ground simultaneously due to the uniform acceleration of gravity. However, if a projectile is launched downward, it will reach the ground before one that is simply dropped, as it possesses initial kinetic energy. In real-world scenarios, air resistance affects the trajectory, but the consensus indicates that the dropped projectile will hit the ground first due to the curvature of the Earth increasing the distance for the horizontally launched projectile.

PREREQUISITES
  • Understanding of gravitational acceleration and its effects on falling objects
  • Familiarity with the concepts of kinetic and potential energy
  • Knowledge of projectile motion principles
  • Awareness of air resistance and its impact on motion
NEXT STEPS
  • Research the principles of gravitational acceleration in different environments
  • Study the effects of air resistance on projectile motion
  • Explore the concept of terminal velocity in various mediums
  • Investigate the mathematical modeling of projectile trajectories
USEFUL FOR

Physics students, educators, and anyone interested in understanding the dynamics of projectile motion and the effects of gravity and air resistance on falling objects.

In a vacuum, if you horizontally launch a projectile or drop it from rest it will hit the ground at the same time.

What about in reallity? IF you shoot a bullet horizontally or drop a bullet from the same height, which will hit the ground first and why?
 
Physics news on Phys.org
you have to state which direction horizontaly you are launching these objects.

if you were to launch it down in a vacuum then the luanched projectile would hit the ground before the on ehtat you dropped because it started with kinetic energy while the one that is dropped has full poteintial energy.

the same would happen in reality, the only differnce is that in the vacuum there would be no air resistance on the object so if it had a terminal velocity it would be much higher.
 
This was dealt with fairly extensively in a previous thread here, but my search feature doesn't go back far enough to find it. I believe the consensus was that the dropped one will hit first because the curvature of the Earth would give the horizontal one more distance to fall.
