Pretend you are a teacher preparing a quiz for the text I will provide. 
            Each quiz question should follow the format below. 
            Ensure that you carefully recheck the questions and answers for accuracy. 
            The output should be a ready-to-use list of dictionaries for the Python eval function:

            [

                    "question": "WRITE THE QUESTION HERE",
                    "options": ["A) OPTION_1", "B) OPTION_2", "C) OPTION_3", "D) OPTION_4"],
                    "answer": INDEX_OF_CORRECT_ANSWER_IN_OPTIONS_LIST,

            ength is proportional to the strength or magnitude.
Mass is a scalar quantity (has magnitude only). 


Newton's first law of motion:
"an object continues in a state of rest or in motion at a constant velocity (constant speed in a constant direction), unless compelled to change that State by a net force.
Note:
Often, several forces act simultaneously on a body, and the net force is the Vector sum of all of them.
Inertia and mass:
Definition: inertia is the natural tendency of an object to remain at rest or in Motion at a constant velocity.
Definition: mass of an object is a quantitative measure of inertia.
SI unit of inertia and mass: Kilogram (Kg).
Newton's third law:
"Whenever an object exerts a force on a second object, the second object exerts an oppositely directed force of equal magnitude on the first object. 
 
Normal force:
Definition: the normal force FN is the force that a surface exerts on an object with which it is in contact, and its direction is perpendicular to the surface. 
Frictional force:
Definition: frictional force is a force acting on the object when the object moves or attempts to move along the surface. 
 
Note:
Direction of frictional force is parallel to the surface and opposing the direction of motion.
Tension force:
Definition: forces are applied by means of cables or ropes that are used to pull an object.
Equilibrium:
Definition: an object is in equilibrium when it has zero acceleration.
Note:
a= zero
according to newton's second law 
∑Fx= zero
∑Fy= zero
∑F = zero
Mechanical Advantage of Levers
Levers are normally used to make physical work easier, to move something that is heavy, or to move something quickly. When we exercise most of our movements will involve the use of levers. For example, when we run, lift weights, kick or throw a ball, all of these actions will involve the use of levers. A lever system within the body would use a lever (bone) to move an object, for example, when we run we are the object being moved, but when kicking a ball, the object being moved is the ball.

Second Class Lever
A second class lever is a lever in which the load is between fulcrum and force, The fulcrum is at one end of the lever. The fulcrum is usually closer to the load, The closer the load is to the fulcrum, the easier the load is to lift, think of a wheelbarrow the long handles of a wheel barrow are really the long arms of a lever.
Third Class Lever
A third-class lever is a lever in which the force is between fulcrum and load. The mechanical advantage of a 3rd class lever is always less than 1. For this class of levers, the force is higher than the load, which is different from second class levers and some first-class levers. Such levers do not have good mechanical advantage, in fact they have mechanical disadvantage.
We can classify the mechanical advantage as:
The mechanical advantage of first-class lever either larger or smaller than 1,
The mechanical advantage of second-class lever is always larger than 1.
