SUMMARY

Constant acceleration in elliptical motion is indeed possible, but it does not result in a circular path unless specific conditions are met. The discussion clarifies that while a constant magnitude of acceleration perpendicular to the velocity vector leads to circular motion, elliptical paths can also be achieved under constant acceleration conditions. This highlights the complexity of motion dynamics in non-circular trajectories.

PREREQUISITES
  • Understanding of basic physics concepts, particularly Newton's laws of motion.
  • Familiarity with kinematics and the equations of motion.
  • Knowledge of elliptical geometry and its properties.
  • Basic mathematical skills for solving equations related to motion.
NEXT STEPS
  • Research the principles of elliptical motion in classical mechanics.
  • Explore the mathematical derivation of acceleration in elliptical orbits.
  • Study the differences between circular and elliptical motion dynamics.
  • Learn about the applications of constant acceleration in real-world scenarios, such as satellite orbits.
USEFUL FOR

Students studying physics, educators teaching motion dynamics, and anyone interested in the mathematical principles of motion in elliptical paths.

G'day all,
I was doing some maths homework and found the acceleration of a particle moving in an ellipse to be constant. Is this correct?

I would have thought that a constant acceleration would give a circle.

That would only be correct in certain special cases (and the particle speed would not be constant). Your intuition was somewhat correct - a constant (magnitude) of acceleration perpendicular to the velocity vector of an object will lead to a circle, but a circular path isn't the only possibility with constant acceleration.
 
Thanks
