Mechanics Flashcards
1
Q
In rotational motion, which direction is positive?
A
Counterclockwise.
2
Q
How do you linearise angular quantities?
A
Multiply by r.
3
Q
When the angular velocity is constant, we have…
A
… uniform circular motion.
4
Q
Centripetal acceleration is…
A
… a centre-seeking acceleration.
5
Q
What happens during non-uniform circular motion?
A
v changes in magnitude as well as direction.
6
Q
What is the tangential acceleration?
A
The acceleration that works in the same direction as v.
7
Q
What does radial acceleration do?
A
Changes the direction of the tangential velocity.
