Renny noticed that after oiling his skateboard wheels, it was easier to reach the speeds he needed to perform tricks. How did the oil help?
A:The oil reduced friction between the moving parts of the skateboard.
B:the oil increased the friction between the moving parts of the skateboard
C:the oil reduced friction between the skateboard wheels and the ground.
D:the oil increased the friction between the skateboard wheels and the ground.
It cant be B or D and I think it is A. Thank you
increased friction makes it slower and tighter
The answers to the test is:
1. B
2. C
3. A
4. A
5. D
I took it and got a 100%. This works for Connexus students too. :D
Those answers are for 8th graders btw.
You're correct! The answer is A: The oil reduced friction between the moving parts of the skateboard.
When Renny oiled his skateboard wheels, it allowed for smoother movement by reducing the friction between the various moving parts of the skateboard, including the wheels on the axles and the bearings inside the wheels. Friction is the force that opposes motion, and by reducing it, the skateboard experiences less resistance as it rolls and spins, making it easier for Renny to reach the speeds needed to perform tricks. So, by reducing friction, the oil helps improve the skateboard's overall performance.
