What science ideas did you learn?
This week we learned about Newton's third law- which is when two objects collide, the force that is exerted on both objects is the same in magnitude and they both move in the opposite direction.
How did you learn these ideas?
We discussed and did an experiment. We saw Laura and Kathy both sitting on carts in the opposite directions, facing each other. Kathy pushes Laura's knees as hard as she can and Laura moves. Kathy moves as well. This means that Laura must have pushed Kathy too. This proves that Newton's third law is correct.
Why is it important to know this idea ?
It is important to understand Newton's third law because we should know what happens when someone is pushed and why the other person who is the pusher moves too.
