Equilibrium means

• forces that are not the same

• forces pushing on something making it move

• equal - both sides of the diagram have equal, opposite forces applied to them

• one side of the diagram has more force being applied than the other

The combination of all the forces acting on an object

• pushes

• pulls

• net force

• unbalanced force

Vectors are

• war heros

• arrows in a force diagram that show the direction of a force

• the measurement of length

• Special swords that bad guys use

Pictures with vectors that show the amount of force being applied to an object =

• Force Diagrams

• Speed diagrams

• Velocity Diagrams

• Math calculations

Forces that cancel each other out because they are the same amount but going opposite directions

• Unbalanced forces

• Net force

• Balanced forces

• Force

Forces applied to an object in opposite directions that are not equal in size

 

• Balanced Forces

• Net Forces

• Force

• Unbalanced Forces

The tendency for objects in motion to resist changes to their direction and speed.

 

• Inertia

• Motion

• Speed

• Velocity

Motion means....

• To stop

• To take a rest

• To change position

• To sleep

Newton's First Law of Motion says.....

• That once moving, something will always stop

• That you cannot stop anything from moving

• that something sitting still will stay still, and something moving will keep moving in the same way unless a force changes its motion

   

• That something moving will stop and that something not moving will never move again.
