If the gravitational force of the Earth suddenly disappears. The weight of the object will become zero, but the mass will remain the same. Weight is dependent on gravity, while mass is an intrinsic property unaffected by gravitational force changes.
A tennis ball bounces higher on a hill than on a field because Earth’s gravitational acceleration decreases on mountains. This decrease in gravitational force results in the ball experiencing less downward force, allowing it to bounce higher compared to a ...
The approximate height of a synchronous satellite from the Earth’s surface is 36,000 km. Synchronous satellites orbit the Earth at this altitude, matching the Earth’s rotational period, and appearing stationary relative to a fixed point on the Earth’s surface.
The ball dropped from an artificial satellite revolving around the Earth will continue to revolve around the Earth in its orbit with the same period of time as the satellite. Gravity keeps the ball in orbit, following the same path ...
A person sitting in a lift feels that his weight is more when the lift is going up at an accelerated speed. During upward acceleration, the lift floor exerts an additional force on the person, making them feel heavier due ...
When a stone is brought from the surface of the moon to the Earth, its mass will remain the same, as mass is an intrinsic property unaffected by gravitational fields. However, its weight will change due to Earth’s stronger gravity, ...
If a body is thrown from the Earth with a velocity of 11.2 km per second, then the body will never return to the Earth. This velocity exceeds the escape velocity of Earth, ensuring that the body will continue moving ...
The period of a Geostationary Satellite is 24 hours. A geostationary satellite orbits the Earth at the same rate as the Earth’s rotation, completing one orbit in 24 hours. This allows it to appear stationary relative to a fixed point ...
With 11.2 km/s minimum velocity will a rocket overcome the Earth’s gravity and go into space when launched from the Earth’s surface. This velocity is known as the escape velocity, the minimum speed required for an object to break free ...
