Physics Question on Acceleration
What determines the nature of the path followed by the particle?
A
Speed
B
Velocity
C
Acceleration
D
Both (b) and (c)
Answer
Both (b) and (c)
Explanation
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 particle's velocity changes, 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 and acceleration, the path could be a straight line, circle or a parabola.
