Q
What causes the acceleration towards the centre of the circle?
A
Centripetal force
1
Q
What is interesting about circular motion and why is this true?
A
The velocity is constantly changing because velocity is a vector and the direction of travel is constantly changing
This means that the object is accelerating towards the centre of the circle
2
Q
What 3 factors affect centripetal force?
A
There has to be a larger centripetal force:
If the object is moving faster
If the object has a larger mass
If the circle is smaller
3
Q
What are the 3 most common types of centripetal force?
A
Tension
Gravity
Friction
