Question

A diagram shows how gravity on Earth works on an object located in different spots in a seaside community. Where is gravity between Earth and an object the strongest?

when the object is on top of a telephone pole
when the object is on top of a telephone pole

when the object is on the highest branch of a pine tree
when the object is on the highest branch of a pine tree

when the object is on top of a nearby mountain
when the object is on top of a nearby mountain

when an object is at sea level

Answer 1

Gravity is generally strongest at sea level compared to higher altitudes because gravitational force decreases with distance from the center of the Earth.

- When the object is on top of a telephone pole: The height is relatively small compared to Earth's radius, so the effect on gravity is minimal.
- When the object is on the highest branch of a pine tree: Similarly, this height is also relatively insignificant in terms of the distance from Earth's center.
- When the object is on top of a nearby mountain: While this is a greater elevation, gravity is still weaker compared to sea level.
- When an object is at sea level: This is where gravity is at its strongest compared to the other locations mentioned.

Therefore, the answer is **when an object is at sea level**.
