True, for example, sound waves are known for vibrating and they move up and down in a particular pattern depending on the pitch and volume. :) Hope this helps x
While the boy is sitting on the chair it creates a force downward on the chair and therefore the chair takes it and gives off the equal amount of force. So while he is putting force downward the chair is putting the same force upward.
Answer:
Please find the answer in the explanation.
Explanation:
To describe a situation in which you exert a force on something and it does not move, you need to Identify the action force and the reaction force, the relative size of the forces, and the objects they act on.
The magnitude of the static friction between the object and the ground is larger than the magnitude of the force applied.
The object will not move if the magnitude of the static friction is greater than the magnitude of the force applied.
The action force is the force applied while the reaction force is equal to the frictional force between the object and the ground.
