Balanced forces

• forces on all sides are equal; net force= 0; an object’s motion will not change

• any push or pull on an object

• forces are not equal; net force does not equal zero; an object’s motion will change

• a force that resists motion when two surfaces are touching each other

Unbalanced forces

• the overall force on an object

• forces on all sides are equal; net force= 0; an object’s motion will not change

• forces are not equal; net force does not equal zero; an object’s motion will change

Law of Inertia

• the force of an object is equal to its mass multiplied by its acceleration (It takes more force to accelerate an object with more mass)

• for every action there is an equal and opposite reaction

• an object at rest will remain at rest and an object in motion will remain in motion until acted upon by an unbalanced force

• the total distance an object travels divided by the total time traveled

Law of Acceleration

• any object at rest will remain at rest and an object in motion will remain in motion until acted upon by an unbalanced force

• for every action there is an equal and opposite reaction

• the distance an object travels per unit of time

• the force of an object is equal to its mass multiplied by its acceleration (It takes more force to accelerate an object with more mass)

Law of Action-Reaction

• for every action there is an equal and opposite reaction

• the force of an object is equal to its mass multiplied by its acceleration (It takes more force to accelerate an object with more mass)

• any object at rest will remain at rest and an object in motion will remain in motion until acted upon by an unbalanced force

• any change in velocity which includes speeding up, slowing down, or changing direction
