State two characteristics of forces at a distance.
Answers
Characteristics of Force:
Forces are due to an interaction of at least two objects. It may change the state of motion of an object. It may change the shape of an object. Forces applied on an object in the same direction add to one another and the resultant is in the same direction.
Newton's Third Law of Motion describes the characteristics of a reaction forces: air of action/
1. The two forces are equal in magnitude.
2. The two forces push or pull in opposite directions.
3. The two force act on different object.
The force of one object is acting on a second object and vise-versa.
4. The description of one force is the reverse of the second force's description.
Example:
A book is placed on a table.
The book pushes down on the table with a force (Fb).
The table pushes up on the book with an equal force (Ft).
