• A sound

• Mass x acceleration

• A color

what is newtons 1st law

• 1. An object that is in motion wants to stay  in motion  and an object at rest wants to stay at rest until acted on  by an unbalanced force.

  
  

•   It takes a larger  force  to move a larger mass than a smaller mass, two things that affect acceleration. 

  
  

• For every action there is an equal and opposite reaction

  
  

what is a net force

• total forces being applied

• type of force

• a force being applied in one direction

• a force being applied in two directions

what is newtons 3rd law of motion

• For every action there is an equal and opposite reaction

  
  

• motion tends to remain in that state of motion unless an external force is applied to it.

• directly proportional to the net force acting on it and inversely

• an object is equal to the mass of the object multiplied by its acceleration.

3 things a force can do

• speed somthing up

  
  

• levitating objects, tricking minds, and seeing things before they happen.

• change the object's direction

• slow something down

if something is in motion but at a steady speed, are the forces balanced.

• yes

• mabye

• no

• unsure

what is newtons 2nd law of motion

• It takes a larger  force  to move a larger mass than a smaller mass, two things that affect acceleration. 

• It states that the acceleration of an object is proportional to the net force applied to it.

• It states that the force applied to an object is equal to its mass multiplied by its acceleration.

• It states that the acceleration of an object is inversely proportional to its mass.

if something is at rest, are the forces acting on it balanced

• yes

• no

• maybe

• not sure

Newtons (N)

• any push or pull on an object

• the units used for force

• the overall force on an object

• a force that pulls all objects that have mass toward one another

how are Mass Force and Acceleration connected

• Force= Mass x Acceleration

• Length x width = height

• Mass is proportional to Acceleration.

• Force is inversely proportional to Acceleration.
