Question

newtons third law of motion practice problems
newtons third law of motion states that for every action, there is an equal and opposite reaction. this law is also known as the law of interaction because it involves two objects that are in contact. in other words, when two objects interact, there is an action force and a reaction force. object a exerts an action force on object b, while the object b exerts a reaction force on object a. the action force and reaction force have the same magnitude but they act in the opposite direction. for example, if a ball hits the ground with a force of 10 n down, then the wall hits the ball with a force of 10 n up. also, if a skater pushes on the wall with a force of 125 n right, then the wall pushes the skater with a force of 125 n left.
part a: answer the questions below about newtons third law of motion.

1. according to newtons third law of motion, what are the two forces that interact called?
2. the magnitude of the action force is the ___________ as the magnitude of the reaction force. for instance, if a person pushes a chair with a force of 50 n, then the chair is pushing back with a magnitude of __________.
3. the action force always acts in the ___________ direction as the reaction force. for example, if a person pushes a chair with a force of 50 n left, then the chair is pushing back with a force of 50n __________.
4. there are two objects, a baseball and a bat. the action force is the baseball hitting the bat to the right. what is the reaction force?
5. there are two objects, a bowling ball and a pin. the action force is the bowling ball hitting the pin to the right. what is the reaction force?

Explanation:

1. Según la ley, son la fuerza de acción y la fuerza de reacción.
2. La magnitud de la fuerza de acción es igual a la de la fuerza de reacción. En el ejemplo, la silla empuja hacia atrás con 50 N.
3. La fuerza de acción actúa en dirección opuesta a la fuerza de reacción. Si se empuja hacia la izquierda, la reacción es hacia la derecha.
4. La fuerza de reacción es el bate golpeando la pelota de béisbol hacia la izquierda.
5. La fuerza de reacción es el alpin de bowling golpeando la bola hacia la izquierda.

Answer:

1. Fuerza de acción y fuerza de reacción.
2. Igual; 50 N.
3. Opuesto; derecha.
4. El bate golpeando la pelota de béisbol hacia la izquierda.
5. El alpin de bowling golpeando la bola hacia la izquierda.
