Name 3 things that use circular motion
The Earth orbiting the sun, hammer throw and some fairground rides
1 of 7
What is needed to act on an object to go round in the circle?
A resultant force, called centripetal force
2 of 7
What does centripetal force do?
Pulls an object towards the centre of the circle
3 of 7
What is centripetal force in space called?
Gravity
4 of 7
What is the velocity like in circular motion and why?
It's always changing because the object is always changing direction
5 of 7
What is the result of the velocity always changing?
The object accelerates
6 of 7
Name 3 factors affecting centripetal force
1. The mass of the object increasing 2.The speed of the object increasing 3. The radius decreasing
