Newtons law Flashcards
What are newton’s three law
1st- Remains at rest
2nd - Force= mass times acceleration
3rd- Equal and opposite reaction force
Compare and contrast unbalanced and balanced force
Objects acted upon by balanced forces stay at rest or move at a constant velocity. Unbalanced forces are forces that are not equal in magnitude and may or may not act in the same direction.
What can an object be doing if the forces are balanced?
Not moving or moving at a constant speed
What law does Inertia relate to and what is Inertia’s definition
1st
Natural tendency of objects in motion to stay in motion
How are gravity and weight related
the weight of an object is determined by the pull of gravity on it.
What is the label for weight
Newtons
What can change, mass or weight
Mass always stays the same, but weight can change depending on how much gravity is acting upon an object
What is the acceleration of gravity on earth
9.81 m/s/s
What is an action and reaction force? Give three examples
