Circular Motion

Question 1

Inertial Frame of Reference

Answer 1

Any frame in which Newton’s Laws hold true + which are moving at a constant velocity wrt another inertial frame.

Question 2

Non-Inertial Frame of Reference

Answer 2

Any frame in which Newton’s Laws do not apply + which accelerate wrt an inertial frame of reference.

Question 3

Fictitious Forces

Answer 3

A name given to any “false force” which doesn’t really exist. These forces will never be drawn in a FBD.

Question 4

Uniform Circular Motion

Answer 4

Occurs when an object moves at a constant speed around a given radius.

Question 5

Centripital Force - F[c]

Answer 5

Is the net force and might be caused by a variety of different forces. Fc = ma, or Fc = any a[c] equation multiplied by m.

Question 6

F[G] Force of Attraction

Answer 6

FG = GMm/r^2

Question 7

Apparent Weight

Answer 7

When you stand on a scale, you feel a normal force (mg) pushing up on you.

Question 8

Artificial Gravity

Answer 8

When “earth gravity of #g” is mentioned, multiply #(9.8) and sub into equation of Fnet = F[N]

Question 9

Extras

Answer 9

Look for things like gravitational energy and kinetic energy in formula sheet under Energy, or respective topic.
