What is v= u + at?

H1. What is v= u + at?

• There are three equations of motion.

1.    v = u + at
2.  s = ut + ½ at²
3. v² = u² + 2as

• Out of these v = u + at is the first equation of motion
• In this equation v = u + at

• u – initial velocity
• v – final velocity
• a – acceleration
• t – time period

• The acceleration of any body is defined as the rate of change of velocity
• Hence, we can write acceleration mathematically in the following way:

• If we rearrange the above equation, then we easily get the desired equation of

• It can also be derived using the velocity-time graph
