Question 1 of 10

Medal-premium 1

A moment is ______.

Select one of the following:

  • the force with which a mass is attracted toward the center of the earth

  • the result of mass x acceleration

  • a body’s capacity to do work

  • created when a force is applied at some distance from an axis or fulcrum, producing
    rotation about that point

  • Density

  • Power

Question 3 of 10

Medal-premium 1

Potential energy is ______.

Select one of the following:

  • the ability of a body to do work due to its motion

  • dependent on mass and velocity

  • a scalar measure of a body’s capacity to do work

  • the ability of a body to do work due to its position or state of being

Question 4 of 10

Medal-premium 1

The Law of Interaction states ______.

Select one of the following:

  • “For every action there is an equal and opposite reaction.”

  • “A body at rest tends to stay at rest.”

  • “Two opposite forces cannot interact.”

  • “An unbalanced force acting upon a body produces an acceleration in the direction of the force that is directly proportional to the force and inversely proportional to the mass of the body.”
