Force and Motion

a force that slows or stops when two things rub against each other

• force

• friction

• gravity

• inertia

when 2 equal forces act in opposite directions the result is that forms are equal and there is no change.

• friction

• balanced forces

• unbalanced forces

• force

Until a force happens, objects at rest will stay at rest and objects in motion will stay in motion.

• Inertia

• balanced forces

• friction

• gravity

• push

• pull
