 | So we had some debate over whether when two things come in contact if they're both exerting forces on each other. If only one is moving, how can something that isn't moving exert a force on something else? We used push and pull spring scales to figure this out! And we realized that no matter what, forces that occur in pairs with no movement are equal. This was so intriguing to us! But all this equal and opposite force stuff is making us wonder about all the collisions we experience, like where the speeds and masses are different. What if something's going faster? Is bigger? What effect does this have on the forces? |
Investigations dealing with different speeds and masses and what this means for the forces in the collisions!
