Question
Show all calculations. If you do calculations on a spreadsheet, the calculation will then C an integral part of the spreadsheet and need not be shown here. Give an example of something in your house based on the concept of centripetal force. Give an example of something in a public park based on the concept of Centripetal force. Convert two revolutions into degrees and radians. Convert 1/4 of a revolution into degrees and radians. Convert 45 degrees into radians. Express the circumference of a circle in terms of its diameter. Express the area of a circle in terms of its diameter.Explanation / Answer
6) Fan and clock
7) When you take your car around a curve a centripetal force must be applied. In this case a combination of Normal Force and Static Friction acting at the tires contribute to keep the car in its circular path.
8)
1 revolution is equal to 360 degree
2 rev = 720 degree.
1 revolution equal to 2pi radians.
2 rev = 12.5664 radians
9)
1/4rev = 90 degree
1/4rev = 1.570796 radians
10)
45 degree = 0.785398 radians
11)
circumference = 2pi*r ..........(d = r/2)
circumference = 4*pi*d
12)
Area = pi*r^2 ..................(r = 2d)
A = 4*pi*d^2
