Multistage rockets are used in launching satellites to gradually increase velocity. Each stage provides thrust, discarding parts when no longer needed, making the process more efficient. Class 11 Physics Gravitation CBSE EXAM 2024-25
A satellite is an object that orbits a planet or celestial body, either naturally (like moons) or artificially (human-made). Class 11 Physics Gravitation CBSE EXAM 2024-25
For a black hole, the radius must be less than or equal to the Schwarzschild radius. Radius depends on mass. Class 11 Physics Gravitation CBSE Exam 2024-25
Escape velocity is the minimum speed needed to leave Earth’s gravitational pull. It’s derived using energy conservation, dependent on Earth’s mass and radius. Class 11 Physics Gravitation CBSE Exam 2024-25
Gravitational potential is work per unit mass. Gravitational potential energy equals gravitational potential multiplied by the body’s mass. Class 11 Physics Gravitation CBSE Exam 2024-25
Gravitational potential is the amount of work required to bring a unit mass from infinity to a specific point in a gravitational field without acceleration. It is a scalar quantity, meaning it has magnitude but no direction. Class 11 Physics Gravitation
Gravitational potential energy depends on work done to bring a body from infinity to a point, reflecting Earth’s gravitational attraction. Class 11 Physics Gravitation CBSE Exam 2024-25
Gravitational potential energy is energy due to position in a gravitational field. Zero level is at infinite separation from masses. Class 11 Physics Gravitation CBSE Exam 2024-25
Gravitational field intensity is the force per unit mass, matching acceleration experienced by a freely falling body under gravity. Class 11 Physics Gravitation Session 2024-25
