Pendulum clocks become slow in summer because the length of the pendulum increases due to thermal expansion, causing the time taken for one oscillation to increase. This change in length affects the clock’s timing mechanism, resulting in slower timekeeping during ...

The time period of a pendulum depends on its length. The longer the length of the pendulum, the longer the time it takes to complete one oscillation. Mass, temperature, and time do not affect the time period of a pendulum.
The fraction of the Earth’s gravity that is closest to the Moon’s gravity is 1/6. The gravitational acceleration on the Moon’s surface is approximately 1/6th of that on the Earth’s surface, making it the closest fraction among the options provided.
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 ...
