padilas [110]

Answer:

            No, in science their meanings are not the same as their everyday meanings.

Explanation:

                   In Science, Precision and Accuracy are defined as,

Accuracy:

               Accuracy is the value which is closest to the known or standard value.

Precision:

                While, Precision is the value of closeness of two measured values to each other.

Example:

             Let suppose in Chemistry Lab you weight an object as 50 g. While the actual weight of that object is 30 g. It means your reading is not accurate.

             On second measurement you find that the object weight is 31 g. This time your reading is not precise.

Every spring has an equilibrium position. Which statements describe a spring at its equilibrium position? Check all that apply.
rjkz [21]

The statements describe a spring at its equilibrium position is the elastic potential energy is zero, the displacement of the spring is at a maximum and the net force acting on the spring is zero.

<h3>What is the equilibrium position?</h3>

A body is in equilibrium when the sum of all forces acting on it equals zero. According to Newton's First Law, when resulting from the laws that act on a body that remains in a state of restriction or in motion in its motion, it remains uniformly null.

In this case the only statements that match the definition of equilibrium position are:

  • The elastic potential energy is zero.
  • The displacement of the spring is at a maximum.
  • The net force acting on the spring is zero.
