When a magnet attracts an object, what force is being applied?
300
Repel
What is it called when two magnets push away from each other?
300
How fast something moves
What is speed?
300
c) gravity

a) The amount of force affects motions
You blow softly on a ball. The ball crosses a finish line in 8 seconds. You blow hard on the ball. The ball crosses the finish line in 3 seconds. Which of the following can you infer from the activity?
a) The amount of force affects motions
b) The amount of force does not affect motion.
c) You cannot use force to move an object.
400
They are both forces.
How are pushes and pulls the same?
400
False. Opposites attract. Poles, or magnets, that are the same (like north and north) will repel.
True or false. When two magnets are the same, they attract.
400
A force that pulls all things toward the center of the Earth.
What is gravity?
400
b) the ball will go far
If you kick a ball with a lot of force, what will happen?

b) the ball will go far
c) the ball will only move a little bit
400
a) Both students will find that the magnet attracts the paper clips
One student experiments to see if a magnet will attract a steel paper clip. Another students does the same experiment. What will their results be?
a) Both students will find that the magnet attracts the paper clips
b) Both students will find that the magnet does not attract the paper clips
c) The two students will have different results
500
A push because the force you put on the ball moves it away from you.
Is kicking a soccer ball a push or pull? Why?
500
The ends are the same pole. Either both S or both N. I know because poles that are the same repel.
If two magnets begin to push away from each other, what can you conclude about the two magnets?
500
b) a force that slows or stops things that are touching
What is friction?
a) a force that pulls all objects towards the Earth
b) a force that slows or stops things that are touching
c) A force that pushes objects away
500
By applying more force
How can you make an object travel farther and faster?
500
False. A magnet has a magnetic field that allows it to pull objects towards it without touching it.
True or false. A magnet must touch an object to attract it.
