Mention the two poles of a magnet.
South and North
What is energy?
Is the ability to do work or to cause a change.
Which are the three types of particles that an atom has?
Protons, neutrons and electrons.
What is a magnet?
A material that has a magnetic field which works all the time.
Which are the two types of energy?
Kinetic and potential
This particle has a negative charge.
Electrons
Attractive or repulsive force
South and North= ?
South and South = ?
South and North = Attract
South and South = Repel
This energy is created by the movement of electrons which travel through electrical circuits.
Electrical energy
This particle has a positive charge.
Protons
Where can we find magnets?
Refrigerators, rollercoaster systems, compasses, cabinet doors, motors, credit cards.
This energy form is produced as a result of the position and motion of an object.
Mechanical energy
Which objects have a neutral charge?
Table or a chair
What’s the difference between a magnet and an electromagnet?
A magnet is a material which works all the time. An electromagnet is a temporary magnet it works only with a source of power.
This energy form is stored in the bonds of a compound and it can be produced in processes as digestion or combustion.
Chemical energy
How is static electricity made?
Friction is the most common way.
