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, ...
