Question

which situation best demonstrates newtons third law?
a person sleeping on a couch.
a book resting on a table.
a rocket launching upward as gases blast downward.
a car parked in a driveway.
3 multiple choice 1 point
when the rockets fuel burns and blasts downward, the rocket lifts upward. this is an example of:
newtons third law
law of universal gravitation
newtons second law

Explanation:

Newton's Third Law states that for every action, there is an equal and opposite reaction. In the case of a rocket launching, the action is the fuel burning and blasting downward (force exerted by the rocket on the gases), and the reaction is the rocket lifting upward (force exerted by the gases on the rocket). A person sleeping on a couch, a book resting on a table, and a car parked in a driveway are examples of equilibrium (balanced forces, related to Newton's First Law in terms of no - acceleration due to balanced forces). The Law of Universal Gravitation is about the gravitational attraction between two masses. Newton's Second Law is about the relationship between force, mass, and acceleration ($F = ma$).

Answer:

For the first question: A rocket launching upward as gases blast downward.
For the second question: Newton’s Third Law.
