Expert Solution

Step 1

Friction :- It is the hinderance provided to the motion of any object in the opposite direction of motion.

Rolling friction :- It is the resistance offered to the motion of any object in the opposite direction while the object is rolling

Sliding friction :- It is the resistance offered to the motion of any object in the opposite direction while the object is sliding also known as kinetic friction

Fluid friction :- It is the hinderance provided to the motion of any object in the opposite direction of motion by the fluid.

Static friction :- It is the friction offered when the two relative objects are in rest.

Weight :- It is the multiplication of the mass of object and the gravitational accleration of that planet.

Gravity :- It is the pulling force exerted by any planet to an object.
