What is the centre of gravity in an object? | A point in the object through which all the weight of the object appears to act |
What is a stable equilibrium? | The ball will return to the same position if given a slight push |
What is an unstable equilibrium? | The ball will not return to the same position if given a slight push |
What is a neutral equilibrium? | The ball will return to a similar position if given a slight push |
What are two basic ideas to follow to improve the stability of objects? | A wide base and a low centre of gravity, E.g a busen burner |
