newtons 1st law
an object at rest stays at rest, and a moving object stays in motion at a constant velocity unless acted upon by an external unbalanced force.
inertia
what is an unbalanced force.
a push or pull that is not opposed by an equal and opposite force.
Tyler and Maria are playing tug of war and they are both pulling with 50n of force what is the net force.
0N
what is net force.
the way we determine an object force
what is velocity.
the speed and direction of an object.
in what does newtons 1st law apply to
everything
ariana pushed a coach with 50n of force and friction was pushing back with 10n of force how much force is she pushing it with.
40N
what is a balanced force.
when two or more forces acting on an object are equal in magnitude (strength) and opposite in direction, resulting in a net force of zero
in what grade do you learn about net force in katy.isd
6th grade.
The ball went 200 meters per minute east what velocity did it go
200m/m east
what does newton discovering his 1st law help us understand
The way objects move and rest.
why do we need unbalanced forces on earth.
they are the only way to change the motion, speed, or direction of any object.
if everyone in the world was playing tug of war and both team were pulling with 1,212,765n what would be the net force.
0N
what does net force help us understand.
how an object's motion will change by combining all individual pushes and pulls acting on it into a single overall force.
The skateboard is going 600m/m a minute north
600m/m north
how did newton find out about his 1st law.
he got his idea about his 1st law by philosophers, Galileo, and Rene Descartes.
what would happen if there was no unbalanced forces.
If no unbalanced forces act on objects, their state of motion will never change.
why do we need balanced force.
to prevent unwanted motion an to keep things steady.
why is net force so important
it determines how an objects motion changes.
why is velocity important.
cause it's everywhere
what would happen if newtons 1st law didn't exist
objects would experience no inertia and move naturally.
georgina is pushing a cube with 867n of force and Fran is helping her and pushing it with 868n of force how much
1,735N
what would happen if there was no balanced forces.
not zero, which causes the object to accelerate and change its state of motion
why is net force everywhere
without net force their would be no determination of an objects force.
what can we do with velocity.
determines an objects speed and direction
