1.2 - Angular Motion Flashcards
1
Q
how many radians are in a circle?
A
2pi
2
Q
what does a with a small t represent
A
tangential acceleration
3
Q
what is a radian in degrees
A
57.3
4
Q
how do you find the linear equivalent of an angular value
A
multiply by radius
5
Q
where do all objects in radial motion accelerate towards
A
the centre of rotation
6
Q
which direction does an object in circular motion move off in when the central acting force is removed
A
tangentially
7
Q
name 2 synonyms for central force
A
centripetal force, radial force
8
Q
explain why a car can go faster on a banked track than a flat circular track
A
a banked track provides a reactionary central force rather than just friction

A
centripetal/radial/central force
