What is the gravitational field?
Definition: It is the region in which a mass experiences a force acting per unit mass of an object due to gravitational attraction.
What is gravitational field strength?
Definition: It is defined as the gravitational force acting per unit mass of an object.
What is the gravitational field strength near the earth’s surface?
Answer: 10 N/kg
What does gravitational field strength depend on?
Answer: It depends on the size of the object generating the gravitational field and the distance from the object.
