Okay, first question is Which of the following is an example of uniform circular motion?
1.) a rollercoaster going through a vertical loop
2.) any of the planets orbiting the sun
3.) car slowing down while making a left hand turn
4.)your jeans in the spin cycle of the washing machine
I'm pretty sure its 2, but just want to make sure because I'm not positive.
Next onee,
Tides are caused by
1.) differences in the gravitational force of the sun at different points on Earth.
2.) differences in the gravitational force of the moon at different points on Earth.
3.) differences in Earth's gravitational field strength at different points on Earth's surface.
4.) fluctuations in the gravitational attraction between Earth and the moon
Once again, I'm pretty sure its 2.....but I'm a little stuck between that and 4. Ahh!
Annnd finally.....
A rollercoaster goes through a vertical loop where the top portion of the loop is a circular track of 8 m radius. The train of the coaster goes through this portion of the loop at 12 m/s.
a)What is providing this force?
I can't figure out if its the track or if its gravity, I'm pretty sure it's one of those but I can't decide.
Thanks in advance, and help with any of them if not all would be appreciated
