Kinematical Equations
If a body starts with velocity (u) and after time t its velocity changes to v, if the uniform acceleration is a and the distance travelled in time t is s, then the following relations are obtained, which are called equations of uniformly accelerated motion.
The above equations are only applicable for uniformly accelerated motion. For a body moving with non-uniform acceleration these equations can’t be used.
Here we are providing some MCQ questions based on kinematical equations for NEET. Practicing these questions will help you to understand the concept well.
