Force

Force

1. Force??

   • Any Pushing or Pulling interaction that causes an object to move
   • Measure by Netwon
     • Newton??
       • Measuring unit used to measure Force
       • Named after Isaac Newton

2. Net Force

   • It's the difference between any two force that act aganist each others

3. Unbalanced Forces

   • When two forces act aganist each other and one is stronger than the other one
   • Causes motion in the greater force's direction

4. Friction

   • It is the force resisting the relative motion of the surfaces
   • Types fo Friction
     • Static Friction
       • Friction that acts upon objects that aren't moving
     • Sliding Friction
       • Friction between two surfaces that are sliding over each other
     • Rolling Friction
       • When an object rolls across a surface
     • Fluid Friction
       • When a solid object moves through a fluid
   • Strength of friction depends on
     • How hard the surface is pushed togther
     • Type of the surfaces involved

5. Gravity

   • Weight
     • Force of gravity acting on an object on the surface of the planet
   • Free Fall
     • When the only force acting on an object is gravity
   • A force that pulls objects towrods each other
   • Universal Gravity
     • Every object has a gravitational force
   • Factors Afecting Gravity
     • Mass
       • Amount of matter in an object
     • Distance

6. Air Resistance

   • When an object is falling through air experiencing a type of friction which is called Air Resistance

7. Terminal Velocity

   • A falling object reaches the greates velocity
   • Terminal velocity is when Air resistance = Weight of the object

8. Projectile

   • An object thrown

9. Inertia

   • Tendency of an object to resist changing in motion

10. Momentum

    • Laws of Conservation of Momentum
    • Descirbes how strong a moving object is

11. Satellite

    • An object that orbits another object in space

12. Centripetal Force

    • A force that cause an object to move in a circular path

13. Balanced Forces

    • Doesn't cause motion
    • When two forces act aganist each other and they both hae equale amount of force
