## FAQs on Kinematic Equations: Uniformly Accelerated Motion Video Lecture - Physics Class 11 - NEET

 1. What are the three equations of uniformly accelerated motion?
Ans. The three equations of uniformly accelerated motion are: 1. v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time. 2. s = ut + (1/2)at^2, where s is the displacement. 3. v^2 = u^2 + 2as, which relates the final velocity, initial velocity, acceleration, and displacement.
 2. How do I calculate the final velocity in uniformly accelerated motion?
Ans. To calculate the final velocity in uniformly accelerated motion, you can use the equation v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time. Simply substitute the given values into the equation and solve for v.
 3. Can you explain the meaning of each variable in the equation s = ut + (1/2)at^2?
Ans. In the equation s = ut + (1/2)at^2, s represents the displacement, u represents the initial velocity, a represents the acceleration, and t represents the time. The equation calculates the displacement of an object undergoing uniformly accelerated motion, taking into account the initial velocity, acceleration, and time.
 4. How do I find the displacement in uniformly accelerated motion?
Ans. To find the displacement in uniformly accelerated motion, you can use the equation s = ut + (1/2)at^2, where s is the displacement, u is the initial velocity, a is the acceleration, and t is the time. Substitute the given values into the equation and solve for s.
 5. Can you explain the equation v^2 = u^2 + 2as in uniformly accelerated motion?
Ans. The equation v^2 = u^2 + 2as is a relationship between the final velocity (v), initial velocity (u), acceleration (a), and displacement (s) in uniformly accelerated motion. It states that the square of the final velocity is equal to the square of the initial velocity plus twice the product of the acceleration and displacement. This equation can be used to calculate any of the four variables if the other three are known.
