Circular motion and gravitation

Question 1

angular speed

Answer 1

w (angle swept/time taken) w = 2fpi

Question 2

relationship between linear speed and angular speed

Answer 2

v = rw

Question 3

What is the velocity of circular motion with constant linear speed?

Answer 3

changes because there is acceleration

Question 4

How is the…

1. centripetal acceleration
2. velocity

to the path of circular motion?

Answer 4

1. normal (pointing inwards)
2. tangent to circle

Question 5

centripetal force symbol

Answer 5

F

Question 6

gravitational field strength

Answer 6

gravitational force per unit mass experienced by a small point mass placed at that point
