A) Speed
B) Velocity
C) Acceleration
D) None of these
Correct Answer: D
Solution :
The nature of path is decided by velocity, acceleration and its direction. Velocity is the ratio of displacement to time. It is a vector quantity possessing both magnitude and direction when a particles velocity charges, the particle is said to undergo acceleration. The instantaneous acceleration is the derivative of the velocity with respect to time. Acceleration is also a vector quantity, possessing both magnitude and direction. Depending on variation of velocity, acceleration the path could be a straight line, circle or a parabola. Hence, option is correct.
