Circular Motion

Question 1

What is centripetal acceleration?

Answer 1

Acceleration towards the center of the Earth (or object)

Question 2

What is the equation for centripetal acceleration?

Answer 2

a(c) = v^2 / r
r = radius of circle

Question 3

What is the relationship between centripetal acceleration and velocity?

Answer 3

They are perpendicular to each other

Question 4

How do I find velocity given revolutions, radius, and time?

Answer 4

v = (revolutions * circumference) / time

Question 5

How do I find required centripetal force?

Answer 5

F(c) = ma(c)

Question 6

What is Newton’s second law?

Answer 6

F = ma

Question 7

What is the equation for centripetal force?

Answer 7

F(c) = mv^2 / r

Question 8

How do you find centripetal acceleration given T?

Answer 8

4π^2r / T^2
T = time of one revolution

Question 9

How do you find centripetal force given T?

Answer 9

4π^2rm / T^2
T = time of one revolution

Question 10

What is the mass of an objection free fall?

Answer 10

0
