Physics: Edexcel IGCSE, topic 1.3.17

Equilibrium

For an object to be in equilibrium:

In linear motion

In linear motion

  • There must be no resultant force acting on the object.
  • It must be stationary or travelling at a constant speed in a straight line.
In circular motion

In circular motion

  • The sum of the clockwise moments must be equal to the sum of the anti-clockwise moments acting on the object.
  • This means that the object is not rotating or rotates at a constant speed.
