How do you take Velocity from Acceleration?

Click For Summary
SUMMARY

The discussion clarifies that to determine velocity from an acceleration vs. time graph, one must calculate the area under the curve, which represents the change in velocity. It is essential to have the initial velocity or the velocity at a specified time to accurately compute the final velocity. The misunderstanding arises from the assumption that the area directly provides the velocity, rather than the change in velocity.

PREREQUISITES
  • Understanding of acceleration vs. time graphs
  • Knowledge of calculus, specifically integration
  • Familiarity with the concept of initial conditions in physics
  • Basic skills in interpreting graphical data
NEXT STEPS
  • Study the principles of integration in calculus
  • Learn how to calculate areas under curves using definite integrals
  • Explore initial conditions in kinematics
  • Review examples of acceleration and velocity relationships in physics
USEFUL FOR

Students studying physics, educators teaching kinematics, and anyone looking to deepen their understanding of motion analysis through graphical representation.

For my HW question I have to take the velocity from an acceleration vs time graph at a certain time.

How do I do this? I was sure that the velocity was the area underneath the curve but its not coming out right at all.

Please help! Thanks

The area under the acceleration graph gives the change in velocity. You still need to know what the velocity was initially, or at some other specified time.
