Dear student,

Static friction is a force which resists the lateral movement of two objects which are touching each other. A simple example of static friction might be a wooden block sitting on a ramp. Unless sufficient force is exerted, the block will not slide down the ramp, because static friction holds it place and resists sliding. When objects have a high coefficient of friction, it means that a lot of force will be required to break through the force of static friction and create movement, while a low coefficient means that less force will need to be exerted.

All the best.

Dear Nehal

The amount of energy needed must be greater than the coefficient of static friction (a constant variable dependent upon which two materials you have) times the normal force being applied to/by the objects

All the best.
