Just before we move onto the magnets side of things in our ‘force and magnets’ topic, we needed to take a quick look at what might interact with a push or pull force. This interaction happens on different surfaces and it is called friction, meaning some surfaces are easier to move along than others.
We came up with 5 surfaces to test (one of which was wet) and used some special forcemeters to measure the newtons it took to pull the bucket along.
which surface do you think would require the least force?
