Newton’s Third Law: Action & Reaction His third law states that for every action (force) in nature there is an equal and opposite reaction. If object A exerts a force on object B, object B also exerts an equal and opposite force on object A.
Q. What forces act when you sit on a chair?
There are at least two forces acting on you as you sit in the chair. One is the force of gravity which is the Earth pulling you straight down. The other is the upward push of the chair you are in which counteracts the pull of gravity.

Q. What is Newton’s third law equation?
Newton’s third law The third law states that all forces between two objects exist in equal magnitude and opposite direction: if one object A exerts a force FA on a second object B, then B simultaneously exerts a force FB on A, and the two forces are equal in magnitude and opposite in direction: FA = −FB.
Q. What is the force of a book on a table?
There are two forces acting upon the book. One force – the Earth’s gravitational pull – exerts a downward force. The other force – the push of the table on the book (sometimes referred to as a normal force) – pushes upward on the book.
Q. Is a book sitting on a table a balanced force?
The force that the book exerts on the table is a normal force, not a weight force. (The book’s weight doesn’t act on the table, it acts on the book.) It’s equal in magnitude to the weight of the book, again, because of the first law. The book and the table press on each other.
Q. Are the forces balanced or unbalanced?
forces that are equal in size and opposite in direction. Balanced forces do not result in any change in motion. forces: forces applied to an object in opposite directions that are not equal in size. Unbalanced forces result in a change in motion.
Q. Which is the correct order of forces?
Gravitational < electrostatic < weak < strong force.
Q. What is most powerful thing in the world?
Take the world’s most powerful computer, the IBM Roadrunner. With the ability to process 1 million billion calculations per second, this supercomputer has the strength of 100,000 MacBooks combined.
