BOYLANATOR said:You are correct. There is an equation you could use to confirm your answer. If you assume that while the car travels around the bend it is briefly in circular motion, what formula could you use to describe the acceleration?
Would the radius become smaller making the acceleration larger? Correct me if I'm wrongBOYLANATOR said:The first one looks good. Can you see what would happen to the variables in that equation if the corner became sharper?
There would be less friction to keep the car on the road, making the car crash.BOYLANATOR said:Yes. For a bonus, why is the car more likely to slide off the road and crash on the sharper bend?
Ok got it! Thanks for the help!BOYLANATOR said:Right idea, but there's no real reason for the friction to decrease, it's more likely to remain constant...
Circular motion is a type of motion in which an object follows a circular path around a fixed point, also known as the center of rotation. This type of motion is often seen in objects such as planets orbiting around a star or a child riding a merry-go-round.
Centripetal acceleration is the acceleration that an object experiences while moving in a circular path. It is always directed towards the center of rotation and its magnitude is given by the equation a = v^2/r, where v is the velocity of the object and r is the radius of the circular path.
According to Newton's Second Law of Motion, the acceleration of an object is directly proportional to the net force acting on it. In circular motion, the centripetal acceleration is caused by a centripetal force that is directed towards the center of rotation and keeps the object moving in a circular path.
Yes, an object can have centripetal acceleration without changing its speed. This is because acceleration is a vector quantity and consists of both magnitude and direction. In circular motion, the direction of the velocity is constantly changing, resulting in a non-zero acceleration even if the speed remains constant.
Centripetal force is the force that acts towards the center of rotation, while centrifugal force is the apparent outward force that an object experiences when moving in a circular path. Centrifugal force is a fictitious force and does not actually exist, whereas centripetal force is a real force that keeps the object moving in a circular path.
