gravitational force ? explain with the field force with a example
Answers
The lines show the direction of the force that acts on a mass that is within the field. This diagram shows that: gravitational forces are always attractive – the Earth cannot repel any objects. the Earth's gravitational pull acts towards the centre of the Earth....
....The Earth, for example, has more gravity than people. This is why an object that falls is drawn to the Earth and returns to the Earth instead of being drawn to a person and flying at that person. Some examples of the force of gravity include: The force that holds the gases in the sun.
Answer:
It is our common experience that some 'muscular effort or force is required when we lift a bucket of water. A ball pressed by hands produces a change in the shape of the ball. To stop a moving body, some force is required. Thus, force is a push or pull which produces or tends to produce a change
in the state of rest or of uniform motion. Force may produce the following changes:
(i) It can change the speed of an object.
(ii) It can change the direction of motion of an object.
(iii) It can change the shape or size of an object.
