Forces
Friction and Drag
-
-
Friction, forces and air resistance are Contact Forces
-
-
An object will keep moving at a steady speed in the same direction (or stay still) unless a resultant force acts.
The resultant force on an object moving with a steady speed in the same direction is zero. The object is in Equilibrium.
Squashing and stretching
Hooke's Law is where if the extension doubles the force, then the object obeys it
-
When the forces squash an object, they cause Compression
-
When forces stretch an object, they cause Tension
The Elastic Limit is where at some point the spring will not go back to its original length when you remove the force
Turning Forces

-
When an object is in Equilibrium, the sum of the clockwise moments is equal to the sum of the anticlockwise moments, this is the Law of Moments
