Average Velocity, Average Speed, Instantaneous Velocity & Speed, and Acceleration
(Explained simply with examples, case studies, and numericals for NEET, JEE Main & JEE Advanced ) To master Kinematics for exams like JEE and NEET, you need to shift from just memorizing formulas to visualizing how things move . Think of Kinematics as "the grammar of motion"—it describes how an object moves without worrying about why (forces). 1️. Average Speed Definition Average speed is the total distance travelled divided by the total time taken . [Average Speed =Total Distance /Total Time ✔ Key Points Scalar quantity Depends on total path length Direction is not considered 🚗 Example A car travels: 60 km in 1 hour 40 km in 1 hour Total distance = 60 + 40 = 100 km Total time = 2 hours Average Speed = 100 /2} = 50 km/h ⚠ Important NEET/JEE Concept Average speed is NOT the average of speeds. Example: Car travels: 60 km/h for first half distance 40 km/h for second half distance Average speed: v avg =2v 1 v 2 /(v 1 +v 2...
