Circular Motion Flashcards
What is centripetal force?
It is the resultant force causing this acceleration and it is always directly towards the centre of the circle
The centripetal force needed to make an object perform circular motions increases as:
The mass do the object increases
The speed of the object increases
The radius of the circle decreases
A student is writing a cooker around on a piece of string, in a horizontal coracle. What force provides the centripetal force?
Tension in the string
What will happen to the cooker is the string breaks?
The confer will fly off in a straight line at a tangent to the circle
What happens when an object moves in a circle?
It continuously accelerates towards the centre of the circle. This acceleration changes the direction of motion of the body, not the speed
