What is a pole turn in Kho-Kho?
In Kho-Kho, the pole turn involves rotating around a pole using the inner foot as a pivot point. This move enables chasers to change direction swiftly while maintaining balance and speed. Proper execution of pole turns increases tagging chances and keeps the game dynamic by preventing defenders fromRead more
In Kho-Kho, the pole turn involves rotating around a pole using the inner foot as a pivot point. This move enables chasers to change direction swiftly while maintaining balance and speed. Proper execution of pole turns increases tagging chances and keeps the game dynamic by preventing defenders from predicting chasers’ next moves.

What is the role of a chaser in Kho-Kho?
In Kho-Kho, chasers aim to tag defenders by using agility, sharp turns, and team coordination. They work as a unit, anticipating defenders’ movements and closing gaps quickly. Effective chasing requires quick reflexes, proper footwork, and understanding of the game’s rules, making chasers the primarRead more

Without gravitational force, the central force of gravity would not affect a satellite so that it will no longer orbit about the Earth. Gravitational force is what provides the inflected force required for a satellite orbiting to trace a curvilinear path. If that force will be removed, a satellite caRead more
Without gravitational force, the central force of gravity would not affect a satellite so that it will no longer orbit about the Earth. Gravitational force is what provides the inflected force required for a satellite orbiting to trace a curvilinear path. If that force will be removed, a satellite cannot have the tendency to orbit around the earth anymore as there is an inward force to hold and maintain it on a curvilinear trajectory, like a circular or elliptical orbit.
According to Newton’s first law of motion, an object in motion will continue moving in a straight line with constant velocity unless acted upon by an external force. So if the gravitational force were to suddenly disappear, the satellite would stop its curved motion and move tangentially to its original orbit at the same velocity \(v\) it had at the moment gravity vanished.
This tangent motion results because the speed of a satellite at any location on an orbit always points along the tangent of the curve in its trajectory. Without gravitational force, the satellite would just go along this tangent forever. The motion, being rectilinear, could not pull the satellite toward its orbital path or back to Earth, since it would be lacking in a centripetal force. It would drift through space, and Earth’s influence would be felt no longer.

Escape velocity is the minimum speed a particle or object must have to overcome the gravitational pull of a planet or celestial body and leave space without any further propulsion. This velocity depends on the mass and radius of the celestial body (like Earth) and the gravitational constant, but notRead more
Escape velocity is the minimum speed a particle or object must have to overcome the gravitational pull of a planet or celestial body and leave space without any further propulsion. This velocity depends on the mass and radius of the celestial body (like Earth) and the gravitational constant, but not on the mass of the escaping particle itself.
This is because the gravitational force exerted on the particle and the kinetic energy needed to escape are proportional to the mass of the particle. In the case of calculating escape velocity, the mass of the particle cancels out, and a value that depends solely on the properties of the celestial body remains.
For instance, the escape velocity on earth is approximately 11.2 km/s just above the surface, a value applicable to any body, no matter how slight its mass may be—like a stone, a satellite, or a spacecraft. As such, the mass of the escaping particle does not affect the escape velocity in any way; it would be universal for a celestial body.
