SUMMARY

This discussion focuses on understanding acceleration in circular motion, specifically in the context of grade 12 physics problems. The user poses questions about the direction of acceleration when a car changes direction while maintaining constant speed. The correct interpretation is that acceleration always points towards the center of the circular path, regardless of the car's speed. This fundamental concept is crucial for solving problems related to circular motion in physics.

PREREQUISITES
  • Understanding of basic physics concepts, particularly Newton's laws of motion.
  • Familiarity with circular motion and centripetal acceleration.
  • Knowledge of vector components and direction in physics.
  • Ability to interpret physics problems and apply relevant formulas.
NEXT STEPS
  • Study the concept of centripetal acceleration in detail.
  • Learn how to resolve vectors in two dimensions.
  • Practice solving problems related to uniform circular motion.
  • Explore real-world applications of circular motion in vehicles and other contexts.
USEFUL FOR

Students preparing for grade 12 physics exams, educators teaching physics concepts, and anyone seeking to strengthen their understanding of circular motion and acceleration.

I know I know. This question must be uber easy in the eyes of you genius'. But the truth is - I'm taking grade 12 physics when I practically failed grade 11(well, I got 51...I wasn't trying, I swear!) so getting some of the concepts can get very confusing...and frustrating! Nonetheless, I need your help my good physics ebuddies!

1) A car is traveling north when it enters a curve. It maintains a constant speed and leaves the curve traveling east. The direction of the car's acceleration is

a)south -east b)north-east c)east d)south e) the car does not accelerate

I'm pretty sure the answer to thsi question is north east, however, since I never recall answering this type of question, I want to make sure.

2) A car drives with constant speed around a corner. If it enters the corner traveling west and leaves traveling south, the acceleration through the turn is directed south-east.
True or False??

I think its true...but I am not sure! haha



Thanks a tun!

Hi Callistal, welcome to PF.
When ever a particle is moving in a circular orbit with uniform speed, the acceleration is always towards the center of the circle.
