  1. Torque - the turning effect of a force (p. 45)
  2. Equilibrium - a state in which all forces acting on an object are balanced (p. 52)
  3. Lever - a simple machine consisting of a rigid bar that pivots on a fixed point called a fulcrum (p. 57)
  4. Moment of Inertia - a measure of an object’s resistance to changes in its rotational motion (p. 63)
  5. Center of Mass - the point at which the entire mass of an object can be considered to be concentrated (p. 68)
  6. Angular Velocity - the rate at which an object rotates around a fixed axis (p. 72)
  7. Tension - the force transmitted through a string, rope, or cable when it is pulled tight by forces acting from opposite ends (p. 78)
  8. Frictional Torque - the torque produced by the frictional force acting on a rotating object (p. 83)
  9. Moment Arm - the perpendicular distance from the axis of rotation to the line of action of the force (p. 89)
  10. Rotational Inertia - the resistance of an object to changes in its rotational motion (p. 95)

  1. Turning Force - the force that makes an object rotate (p. 45)
  2. Balance - when all the forces on an object are equal and it stays still (p. 52)
  3. See-Saw - a simple machine with a long bar that moves on a point in the middle (p. 57)
  4. Resistance to Turning - how hard it is to make an object start or stop rotating (p. 63)
  5. Middle Point - the spot where all the weight of an object seems to be concentrated (p. 68)
  6. How Fast It Spins - how quickly an object rotates around a fixed point (p. 72)
  7. Pulling Force - the force that goes through a string or rope when it is stretched (p. 78)
  8. Slowing Down Spin - the force that tries to stop a rotating object (p. 83)
  9. Distance from the Middle - how far a force is from the point it makes an object rotate (p. 89)
  10. Resistance to Spin - how much an object resists changes in its spinning motion (p. 95)
