What is Kinetic energy?
the energy that an object has because it is moving
True or False, Magnets attract all metals.
False, some metals don't attract other magnets.
What happens when their is more potential energy in a magnet system?
The magnets have more kinetic energy and in turn more speed.
When you is it called when you move a marble when it was still before?
Start Moving.
What is the study of habitats and life called?
Biology.
What does transfer means?
to move from one object to another or one place to another
Can magnets attract other magnets?
Magnets can attract other magnets.
True or False Is there an infinite amount of energy?
False.
When something is already moving, and you push it more, what is it called?
Speed up.
Whats the closest planet to the sun?
Mercury.
What does isolate mean?
to separate or set apart
Can metals attract other metals?
Metals can't attract other metals because they don't have a magnetic force.
What happens to the potential energy when its changed to kinetic?
It is transferred and converted to kinetic.
What moves faster, a magnet closer to the other magnet, or a magnet that is farther? (repelling magnets)
Magnet closer together.
What is a constellation that is named after a person?
Perseus and Orion.
What does model means?
an object, diagram, or computer program that helps us understand something by making it simpler or easier to see.
Where is the potential energy the highest in a magnetic system?
the field lines closest to the magnet.
Can you lose energy from eating?
You can if you chew long enough and it barely gives you energy.
When they are heading to a direction with a speed of 4cm/s and is slowed down by 10cm/s, what is happening?
It slows down and changes direction.
What does magnetic field lines mean?
a line that connects opposite magnetic poles and represents the strength and direction of the magnetic field.
If you have iron in the middle of two repelling magnets what will happen?
The iron will attach to one magnet and the other magnet will not attach and instead repel in the other direction.
When you release something with 800 potential energy and it hits a wall at full speed (max), how much energy is converted to kinetic energy?
all of it.
If a marble is moving four cm/s and it has momentum(moving faster), and its slowed down by four cm/s, what is happening?
It slows down because since it will be above four cm/s, it won't change direction or stop.
