Python program to calculate acceleration, final velocity, initial velocity and time
  • Difficulty Level : Hard
  • Last Updated : 03 Jan, 2021

Here we can find the acceleration (a), final velocity(v), initial velocity(u) and time(t) using the formula a = (v-u)/t.

At first, functions are defined for all four types of calculations, in which they will accept three inputs and assign the value in three different variables. Then the fourth value is calculated using the acceleration formula and the calculated value is returned. We are going to use the same acceleration formula in different approaches.

Approach: 

  • In the first approach, we will find initial velocity by using the formula “u = (v-a*t)”
  • In the second approach, we will find final velocity by using formula “v =  u + a*t”
  • In the third approach, we will find acceleration by using formula “a = (v – u)/t”
  • In the fourth approach, we will find time by using formula “t = (v – v)/a”

Example 1: Initial velocity (u) is calculated.

Python3




# code
# Enter final velocity in m/s:
finalVelocity = 10
  
# Enter acceleration in m per second square
acceleration = 9.8
  
#Enter time taken in second
time = 1
initialVelocity = finalVelocity - acceleration * time
print("Initial velocity = ", initialVelocity)

Output:



Initial velocity =  0.1999999999999993

 

Example 2: Final velocity (v) is calculated.

Python3




# code
# initial velocity in m/s:
initialVelocity = 10
  
# acceleration in m per second square
acceleration = 9.8
  
# time taken in second
time = 1
finalVelocity = initialVelocity + acceleration * time
print("Final velocity = ", finalVelocity)

Output:

Final velocity =  19.8

Example 3: Acceleration (a) is calculated.

Python3




#code
# initial velocity in m/s
initialVelocity = 0
  
# final velocity in m/s
finalVelocity = 9.8
  
# time in second
time = 1
  
acceleration = (finalVelocity - initialVelocity) / time
print("Acceleration = ", acceleration)

Output:

Acceleration =  9.8

Example 4: Time (t) is calculated.

Python3




# code
#final velocity in m/s
finalVelocity = 10
  
#initial velocity in m/s
initialVelocity = 0
  
#acceleration in metre per second square
acceleration = 9.8
  
time = (finalVelocity - initialVelocity) / acceleration
print("Time taken = ", time)

Output:

Time taken =  1.0204081632653061
