SUMMARY

The discussion focuses on analyzing velocity-time graphs for two scenarios involving an egg: one being dropped from a bridge with an initial velocity of 0 and the other being thrown downward. The first situation corresponds to a curve with a decreasing linear slope starting at the origin, while the second situation features a steeper negative slope. The key point of confusion is determining the sign of the initial velocity for the thrown egg, which is definitively positive, as it is directed downward from the starting point.

PREREQUISITES
  • Understanding of velocity-time graphs
  • Knowledge of kinematic equations
  • Familiarity with concepts of initial velocity and acceleration
  • Basic principles of projectile motion
NEXT STEPS
  • Study the kinematic equation for uniformly accelerated motion
  • Learn about the characteristics of velocity-time graphs
  • Explore the differences between free fall and projectile motion
  • Review examples of initial velocity in various motion scenarios
USEFUL FOR

Students studying physics, educators teaching kinematics, and anyone seeking to understand the principles of motion as applied to real-world scenarios.

Homework Statement


My problem is that I am given a bunch of labelled curves on a velocity-time graph that I have to match up with 2 given situations. The first situation is an egg being dropped from a bridge with no initial velocity. The second situation is an egg being thrown downward off of the bridge.

The Attempt at a Solution


Now, I was able to match up the first situation with the only curve that had a decreasing, linear slope beginning with an initial velocity of 0. For the second situation, it is clear to me that the curve should have a steeper, still negative slope. My problem is that I am not sure whether, in the second situation, the initial velocity is positive or negative. Can someone explain which it is and why it is that?

Hi Schrodes2011, welcome to PF.

Write down the relevant equation used to draw the graphs.
