Centripetal acceleration - ask about proof Flashcards
1
Q
What is centripetal force?
A
the resultant force on an object moving around a circle at constant speed
because it acts in the same direction as centripetal acceleration, which is toward the centre of the circle
e.g. tension in a string
2
Q
What causes centripetal acceleration?
A
the centripetal force
resultant force acting towards the centre of the circle
3
Q
How is the centripetal force equation created?
A
applying Newton’s second for constant mass in the form F = ma
F = mv2 / r = mω2r
