Force
- 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
- Net Force
- It's the difference between any two force that act aganist each others
- 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
- 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
- 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
- Air Resistance
- When an object is falling through air experiencing a type of friction which is called Air Resistance
- Terminal Velocity
- A falling object reaches the greates velocity
- Terminal velocity is when Air resistance = Weight of the object
- Projectile
- An object thrown
- Inertia
- Tendency of an object to resist changing in motion
- Momentum
- Laws of Conservation of Momentum
- Descirbes how strong a moving object is
- Satellite
- An object that orbits another object in space
- Centripetal Force
- A force that cause an object to move in a circular path
- Balanced Forces
- Doesn't cause motion
- When two forces act aganist each other and they both hae equale amount of force
