Force

  1. 1. FORCE -is a push or pull upon an object - any influence that causes an object to undergo a certain change, either concerning its movement or direction
  2. 2. NONCONTACT FORCES are not in contact with - the objects each other. GRAVIT Y
  3. 3. CONTACT FORCES - the objects have to be in contact with each other. Force between road and the tires of a car
  4. 4. KINDS OF FORCES
  5. 5. Gravitational Force attraction, or pull between - It is an objects. - It affects anything that has mass.
  6. 6.  Dependence on Mass  Dependence on Distance
  7. 7.  Dependence on Mass More massive planet = more/large weight Less massive planet = less/small weight
  8. 8.  Dependence on Distance nearer distance = greater gravitational force farther distance = lesser gravitational force
  9. 9. Electromagnetic Force - It is associated with electrical charge and magnetism.
  10. 10. Electromagnetic Force - It causes the interaction between electrically charged particles; - the areas in which this happens are called electromagnetic fields.
  11. 11. Weak Force - It is actually stronger than the gravitational force. - It is active only at distances less -18 than 10 . Strong Force - It acts only on hadrons and keeps them tightly packed within the nucleus.
  12. 12. Frictional Force - It is the resistive force that occurs when two surfaces contact each other.
  13. 13. Tension Force - It is the force that is transmitted through a string, rope, cable or wire when it is pulled tight by forces acting from opposite ends.
  14. 14. Normal Force - It is the support force exerted upon an object that is in contact with another stable object. For example, if a book is resting upon a surface, then the surface is exerting an upward force upon the book in order to support the weight of the book.
  15. 15. Applied Force - It is a force that is applied to an object by a person or another object. - If a person is pushing a desk across the room, then there is an applied force acting upon the object. The applied force is the force exerted on the desk by the person.
