Question

When do we use equation of motion s=ut+1/2at²​

Answer 1

Answer: When we have to calculate displacement, when the values for time, acceleration and initial velocity are known.

Hope it helps you!!

Answer 2

Hi :D

Answer: The second equation of kinematics is used to find distance travelled provided that a particle has a uniform acceleration (or no acceleration), a specific initial velocity and time taken to cover that amount of distance.

Also, another criterion is that the particle should be moving in a straight line and friction is neglected.

Other equations of motion:

• 1st: v = u + at
• 2nd: S = ut + 1/2at²
• 3rd: 2aS = v² - u²
• 4th: Snth = u + a/2(2n - 1). [It is probably new to you. Here, we can find the distance travelled in a particular second, i.e., nth second.]
