Here are the key concepts and notes on Power and Collisions, presented in a simple student-friendly format: “`html Important NEET Exam Concepts Power calculation using P = F · v Conservation of momentum in all collisions Difference between elastic (energy conserved) and inelastic (energy lost) collisions Kinetic energy transfer in elastic collisions (fractional energy loss […]

Here are your physics notes on Power and Collisions, presented in a simple and friendly way! 😊 “`html ⚡ Power: The Rate of Doing Work Power tells us how fast work is done or energy is transferred. Think of climbing stairs: It’s not just how many stairs you climb, but how quickly you climb them!

Here are your friendly physics notes on springs, energy, and more – perfect for building a strong foundation! 😊 “`html Spring Force and Hooke’s Law When you stretch or squeeze a spring, it pushes or pulls back! 🦾 This force is called the spring force (Fs). For an ideal spring: Hooke’s Law says: Fs =

Here are your friendly physics notes on mechanical energy conservation – perfect for high school students! 🌟 “`html Understanding Mechanical Energy Conservation 🔑 Key Concepts for NEET Conservative forces (like gravity/springs) depend only on start/end positions, not path taken. Total mechanical energy (kinetic + potential) is conserved when only conservative forces act. At maximum height

Here are your friendly physics notes on Potential Energy and Conservation of Mechanical Energy, perfect for high-school students! 🌟 “`html What is Potential Energy? Imagine energy that’s “stored” and ready for action! 🏹 That’s potential energy. Examples: A stretched bowstring 💪 (releases energy as an arrow flies). Fault lines in Earth’s crust 🌍 (like compressed

🔋 Work-Energy Theorem for Variable Forces 1. Work Done by a Variable Force When a force changes with distance (e.g., the woman pushing the trunk 🧳), work is calculated by finding the area under the force vs. displacement graph: For a linearly decreasing force (like in Example 5.5): \( W = \text{Area of rectangle} +

🚀 Work Done by a Variable Force When the force applied changes with position, we calculate work using integration (adding up tiny bits of work): For a small displacement \( \Delta x \), work done is \( \Delta W = F(x) \cdot \Delta x \). Total work = area under the \( F(x) \) vs.

Work Work happens when a force causes an object to move. It’s calculated using: \[ W = F \cdot d \cdot \cos\theta \] Where: \( F \) = Force applied \( d \) = Displacement \( \theta \) = Angle between force and displacement When is work not done? 🚫 No displacement: Like pushing a

Work, Energy, and Power Notes 1. Work-Energy Theorem The change in kinetic energy of an object equals the work done by the net force acting on it. Formula: \[ K_f – K_i = W \] where \( K_f = \frac{1}{2}mv^2 \) (final kinetic energy), \( K_i = \frac{1}{2}mu^2 \) (initial kinetic energy), and \( W

Kinetic Energy and Work Kinetic Energy (K): The energy an object has due to its motion. Formula: \[ K = \frac{1}{2}mv^2 \] where \( m \) = mass and \( v \) = speed. Work (W): Done by a force on an object when it causes displacement. Formula for constant force: \[ W = \mathbf{F}
