What is the direction of the acceleration ?

Click For Summary
SUMMARY

The direction of acceleration for an object changing its velocity from east to north is not straightforward. As the object moves around a bend, the acceleration direction varies: it starts as north upon entering the bend, transitions to northwest at the midpoint, and becomes west upon exiting. The average direction of acceleration over the entire bend is northwest. This highlights the complexity of interpreting acceleration in non-linear motion.

PREREQUISITES
  • Understanding of basic physics concepts, particularly kinematics.
  • Familiarity with vector analysis and directionality in motion.
  • Knowledge of circular motion dynamics and centripetal acceleration.
  • Ability to interpret and analyze motion graphs.
NEXT STEPS
  • Study the principles of circular motion and centripetal acceleration.
  • Learn about vector decomposition in physics.
  • Explore the concept of instantaneous versus average acceleration.
  • Investigate the effects of acceleration on passengers in a vehicle during turns.
USEFUL FOR

Students studying physics, educators teaching kinematics, and anyone interested in understanding motion dynamics in real-world scenarios.

Same direction of the velocity -.-
 
That's a rather ambiguous question. Let's assume it's a car going around a bend in the road. Then, at any given moment, the direction of the acceleration is opposite to the way all the passengers are lurching, i.e., sideways towards the inside of the bend. That direction starts off being North as you enter the bend, then it's North West at the middle of the bend, then it's West just as you leave the bend. So what they expect for a one-word answer is a mystery to me. If they want the average of the acceleration over that time period, it's North West. I'd flunk the examiner though.
