FAQs on Derivation of 3 Equations of Motion by Graphical Method Video Lecture - Physics for Class 9

1. What is the graphical method used to derive the equations of motion?
Ans. The graphical method used to derive the equations of motion involves plotting the motion of a particle with time on a graph and determining the slope of the graph at different points. These slopes are then used to derive the equations of motion.
2. What are the three equations of motion derived from the graphical method?
Ans. The three equations of motion derived from the graphical method are: 1) v = u + at 2) s = ut + 1/2 at^2 3) v^2 = u^2 + 2as where v is the final velocity, u is the initial velocity, a is the acceleration, s is the displacement, and t is time.
3. How is the slope of a displacement-time graph calculated using the graphical method?
Ans. The slope of a displacement-time graph is calculated by dividing the change in displacement by the change in time between two points on the graph. Mathematically, slope = Δs/Δt.
4. How is the area under a velocity-time graph calculated using the graphical method?
Ans. The area under a velocity-time graph is calculated by finding the area of the trapezium formed by the graph and the time axis. Mathematically, area = (u+v)/2 x t.
5. How is the acceleration of a particle determined from a velocity-time graph using the graphical method?
Ans. The acceleration of a particle can be determined from a velocity-time graph by calculating the slope of the graph at a particular point. Mathematically, acceleration = slope of the velocity-time graph = Δv/Δt.
