Confused about Grade 12 Physics Questions? Get Help Here!

AI Thread Summary
The discussion revolves around confusion regarding grade 12 physics concepts, specifically related to acceleration and direction during motion. The first question involves a car changing direction from north to east while maintaining constant speed, with the correct answer being that the acceleration is directed towards the northeast. The second question addresses a car turning from west to south, where the acceleration is indeed directed towards the southeast, confirming the statement as true. The key takeaway is that in circular motion, acceleration always points towards the center of the circular path. Understanding these principles is crucial for mastering physics concepts at this level.

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.
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
