Circular Motion
Cards in this deck (12)
- 1What is the frequency of rotation?1
______
Time period - 2What is the speed of a point on the circumference of the circle?circumference
---------------------------
time for one rotation - 3What is angular speed?The angular displacement per seconds, 2π/T or 2πf
- 4What is the unit of ω ?Radians per second
- 5Why are objects in circular motion always accelerating?They are constantly changing velocity as their direction changes so their acceleration does
- 6Which direction does velocity change around the circle?The change in direction of the velocity is always to the centre of the circle
- 7What is centripetal acceleration?The acceleration of the object towards to centre due to changing velocity.
- 8Formula of centripetal acceleration?v^2
--------
r - 9What is the centripetal force?The resultant force on an object which causes the direction of velocity to change keeping it in circular path
- 10What causes the centripetal acceleration?Centripetal force
- 11Show the formula for centripetal force.Centripetal acc = Centripetal F
F = ma
a = v^2/r F=ma
mv^2
-----
r - 12—
