  13. Moment of a Force-I The moment of a force is a measure of its tendency to rotate an object about some point A force applied to a pivoted beam causes the beam to rotate Moment of force W about pivot point: Wxd

  14. Buoyancy Force produced by fluid pressure Gravity When an object is fully or partially immersed in a fluid, due to the pressuree difference of the fluid between the top and bottom of the object, buoyant force acts on the object causing it to float (mass of the object) (density of the object) pobject pfluid (density of the fluid) The net upward buoyancy force is equal to the magnitude of the weight of fluid displaced by the body Buo Buoyancy is important for boats, ships, balloons, and airships

  15. Drag Force Force that resists the motion of an objedt through a fluid Drag force arises from the motion of an object through fluid Drag force arises from the flow of fluid past an object An object moving through a fluid experiences a force in direction opposite to its motion Terminal velocity is achieved when the drag force is equal in magnitude but opposite in direction to the force propelling the object.

  16. Newton's Laws of Motic 1st Law: Every body continues in its state of rest or of uniform motion in a straight line unless it is compelled to change that state by an external force 2nd Law: The rate of change of momentum of an object is proportional to the force acting on the object and is in the same direction as that force 3rd Law: To every action there is an equal and opposite reaction
