A2 Physics Circular Motion
Cards in this deck (11)
- 1Angular displacementThe angle of the arc through which the object has moved from its starting position. Measured in radians or degrees
- 2How to calculate length of an arcr x angle
- 3RadianThe angle subtended at the center of a circle by an arc length equal to the radius of the circle
- 4Angular velocityAngular displacement
-------------------------------------
Time taken - 5Two factors that affect the speed of an object travelling around a circleAngular velocity
Distance from center of the circle - 6How to calculate speed (around a circle)Angular velocity x distance from center
- 7Newton's first lawAn object will remain at rest or at constant state of uniform motion unless it is acted on by a resultant force
- 8Centripetal forcesThe resultant force acting on an object that is moving in a circle
- 9Where is the acceleration in centripetal forcesTowards the center of the circle; following the rule of F=ma where F is the centripetal force
- 10How to calculate accelerationv^2 / r
rw^2 - 11How to calculate centripetal forcesmass x centripetal acceleration
mrw^2
mv^2/r
