COPY IN YOUR SPIRAL PG 67 Objective: Students will identify between the types of newton's laws and devise how to manipulate objects with those forces Homework: Finish lab Juno Practice #2
What causes an object to move? Warm up 10/7-8 What causes an object to move?
“You can not deny the laws of physics jim” Newtons Laws “You can not deny the laws of physics jim”
Obecjts at Rest -Net force of 0 -Lack any movement -Do nothing Draw an object at rest
Objects in motion -Are moving -Net force > 0 -Unbalanced force Draw an example of an object in motion -Are moving -Net force > 0 -Unbalanced force -What might bring an object in motion to become at rest?
Objects and Inertia Object's resistance to change in motion or path of motion More mass = More inertia Draw 3 objects and list them in order of inertia least to greatest
Newton’s First Law An objects in motion will stay in motion while objects at rest will stay at rest. Unless acted on by an unbalanced force
Newton’s Second law An object's acceleration depends on the object's mass and force applied -Greater the mass, the more force it needs to accelerate. -Objects with less mass have an easier time accelerating
Newton’s Third law For every action there is a opposite and equal reaction When objects exert a force, the second object will exert the same amount of force back
