SUMMARY

The discussion centers on calculating the force exerted by a 3.915 kg object falling from a height of 300 mm. It emphasizes the importance of understanding impulse and momentum, particularly how the force varies depending on the surface the object impacts, such as a pillow versus a concrete floor. The maximum force occurs at the moment of impact, and the impulse function's shape is influenced by the maximum force applied during the collision. Accurate quantification of dynamic impact problems is highlighted as a complex challenge.

PREREQUISITES
  • Understanding of Newton's Second Law of Motion
  • Familiarity with impulse and momentum concepts
  • Knowledge of dynamic impact analysis
  • Basic principles of force-time diagrams
NEXT STEPS
  • Study the calculation of force using Newton's Second Law
  • Learn about impulse-momentum theorem applications
  • Research dynamic impact analysis techniques
  • Explore the differences in force exerted on various surfaces during impact
USEFUL FOR

Physics students, engineers, and anyone interested in understanding the dynamics of falling objects and impact forces.

Hello

I have an object of mass=3.915 kg falling down by (300 mm), how can I find the force?

This is the homework area, so I'll assume it's a homework question. Typically in textbooks you are given a force/time diagram, integrated which gives the impulse, or momentum of which a moving object has.

The force is then the value of that graph at any time, with the maximum typically being at time zero, or when the object initially strikes.

However, how the impulse function looks is quite dependent on the maximum force that gets applied. Does a falling object exert the same force falling onto a pillow as it does a concrete floor?

In real life, dynamic impact problems can be quite difficult to quanitify accurately.
