Detailed Solution
Download Solution PDFThe correct answer is (v-u)/t.
CONCEPT:
- Acceleration: The rate of change in velocity is called acceleration. It is denoted by a.
- The SI unit of acceleration is m/s2.
- Equation of motion: The mathematical equations used to find the final velocity, displacements, time, etc of a moving object without considering force acting on it are called equations of motion.
- V = u + at
- Where, V = final velocity, u = initial velocity, a = acceleration of body under motion, and t = time taken by the body under motion.
EXPLANATION:
From the above equation of motion:
V = u + a t
So a = (V - u)/t
- The formula for finding acceleration is (v-u) / t. So option 4 is correct.
Additional Information
- The product of velocity and time (v x t) represents the displacement of a body which represents the shortest distance between two points.
- The reciprocal of time (1 / t) represents the frequency of oscillations which gives the value of the total number of oscillations in the given time.
- The work per unit time (W / t) represents power which is the measurement of the rate of doing work.
