100

to pull together
100
What parts of magnets repel?
north and north, south and south
200
Name an example of a push.
pushing in your chair, throwing a ball, closing a door
200
Which law is this: more force more acceleration?
Newton's second law of motion
200
True or False. Just because a magnet is small does not mean that it is weaker than a bigger magnet.
True. Small magnets can be stronger than bigger magnets. The size does not affect the strength.
200
What does repel mean?
pull away from one another
200
Name two things in this classroom that magnets may stick to.
the door, the whiteboard
300
Name a pull
opening a door, pulling out a chair, pulling a wagon
300
What law is this: an object at rest tends to stay at rest?
Newton's first law of motion
300
What do magnets ALWAYS stick to.
iron
300
What is motion?
change in position as an object is moving
300
Why do magnets only stick to one of our whiteboards?
Because one does not have any iron in it.
400
How does force affect the motion of an object?
When you use force it changes the motion of an object.
400
Which law is this: every action has an equal and opposite reaction?
Newton's third law of motion
400
Name three things magnets do not stick to.
wood, glass, copper
400
What is a pole?
the place on a magnet where the magnetic field is the strongest
400
If you put more force when pushing a toy car down a ramp, what will happen?
it will go farther than if you did not put a lot of force
500
What does speed, position, and distance have to do with force?
When you exert a force on an object it can change the speed, position and the distance an object travels.
500
Which law is this talking about: the ball is moving and it keeps on moving, a pencil it laying on the desk and stays laying on the desk
Newton's first law of motion
500
What two poles on magnets attract to each other?
North and South
500
What is distance?
the amount of space between on place and another
