Linear and Angular motion Flashcards
What is Angular Motion?
Movement of a body or part in a circularpath about an axis of rotation.
How is angular motion caused?
Eccentric force applied outsdie of centre of mass
What is linear motion?
Movement of a body in a straight or curved line
How is linear motion caused?
Ecccentric force applied directly to centre of mass
What is angular momentum?
The qauntity of angular motion possessed by a body
How is angular momentum calculated?
Moment of inertia x Angular velocity
What is angualar velocity?
The rotational speed of an object and the axis the object rotates around.
How is angular velocity calculated?
Angular displacement / time taken
What is Moment of Inertia?
The resistance of a body to change its state of angular motion.
How do you calculate moment of inertia?
sum of ( mass x distribution from axis squared)
What are the units for moment of inertia?
KGM2
