Force

Force. A force is a push or a pull. The combination of all the forces acting on an object is the net force. PUSH. PULL. Force. Two or more forces exerted on an object are balanced forces if their effects cancel each other and they do not change the object’s velocity.

  1. Force A force is a push or a pull. The combination of all the forces acting on an object is the net force. PUSH PULL

  2. Force Two or more forces exerted on an object are balanced forces if their effects cancel each other and they do not change the object’s velocity. If the forces on an object are balanced, the net force is zero.

  3. Force ====

  4. Force If the net force is not zero, the forces are unbalanced forces. Then the effects of the forces don’t cancel, and the object’s velocity changes.

  5. Force Draw an example of both balanced and unbalanced forces on your paper.

  6. Gravity Gravity is the force of attraction between all masses in the universe.

  7. Gravity Depends on the mass of the objects and the distance between them. The gravitational force becomes weaker the farther apart the objects are and also decreases as the masses of the objects involved decrease.

  8. Weight The weight of an object is the size of the gravitational force exerted on an object.

  9. Friction The force that brings nearly everything to a stop is friction, which is the force that acts to resist sliding between two touching surfaces.

  10. Friction Although several different forms of friction exist, they all have one thing in common. If two objects are in contact, frictional forces try to prevent one object from sliding on the other object.

  11. Static Friction The type of friction that prevents an object from moving when a force is applied is called static friction.

  12. Sliding Friction Slidingfriction slows down an object that slides.

  13. Rolling Friction Rolling friction occurs when an object rolls across a surface.
