The acceleration vector has the same direction as instantanous change in velocity. Since the direction of the velocity changes in the direction in which the curve bends ,the acceleration is always pointing towards concavity of the curve
The acceleration in curvilinear motion can also be expressed in terms of two components

Prime Numbers
A prime number can be divided, without a remainder, only by itself and by 1. For example, 19 can be divided only by 19 and by 1.
Interesting facts about prime
•The only even prime number is 2. All other even numbers can be divided by 2.
•If the sum of a number’s digits is a multiple of 3, that number can be divided by 3.
•No prime number greater than 5 ends in a 5. Any number greater than 5 that ends in a 5 can be divided by 5.
•Zero and 1 are not considered prime numbers.
•Except for 0 and 1, a number is either a prime number or a composite number. A composite number is defined as any number, greater than 1, that is not prime.
