Exercise-10.2 Page: 136 ( Gravitation )
1. What do you mean by free fall?
Earth’s gravity attracts each object to its center. When an object is dropped from a certain height, under the influence of gravitational force it begins to fall to the surface of Earth. Such an object movement is called free fall.
2. What do you mean by acceleration Q due to gravity?
When an object falls freely from a certain height towards the earth’s surface, its velocity changes. This velocity change produces acceleration in the object known as acceleration due to letter g denoted gravity.
The gravity-based acceleration value is,
