Question

Weight of an object is the __________________force on the earth acting on the object.​

Answer 1

Weight of an object is the _gravitational_force on the earth acting on the object.

Answer 2

Normal Force

• The force exerted by a surface on an item is the normal force. When an item is at rest, its resultant force is equal to 0; thus, the downward force (weight) must equal the upward force (normal force).

• As weight operates in a downward direction, the result will be negative.

For example,

• If a book is laying on a surface, the surface is exerting an upward force on the book to hold its weight.
