Forces and Interactions Unit Study Guide Answers
Forces and Interactions Study Guide
FI1- I can define electricity and magnetism.
1)Charged particles that are moving through a medium and have the potential to produce a force.
2)A force of attraction due to a magnetic field.
FI2- I can explain the relationship between electricity and magnetism.
3)They both involve moving electrons
4)By looking at how close the magnetic field lines are.
5)By passing an electric current through a coiled wire.
FI3- I can explain interactions and magnitudes of electric and magnetic forces.
6)They repel. Because that forces them farther from neutral or 0.
7)They attract. Because it makes them neutral or 0.
8)They repel. Because the electrons are colliding into each other and push them away.
9)They attract. Because the electrons from the north pole go directly into the south pole.
10)On board
11)On board
FI4- I can use data to determine factors that affect the strength of electric and magnetic forces.
12)Distance and charge. Because when they were changed the results changed.
13)Distance, density and temperature. Because when they were changed the results changed.
14)Not as much current or charge can go through the small wire as the big wire.
15)Yes, increase it.
16)It changes the density of the magnet which our data table shows changes the strength.
FI5- I can describe electromagnets and electric motors.
17)Magnets that use an electric current to produce a temporary magnetic field.
18)Iron core, battery and copper wire
19)A motor produced when an electromagnet is set inside of a permanent magnet.
20)An electromagnet and a permanent magnet.
FI6- I can explain how to modify electromagnets and electric motors.
21)On board
22)On board
FI7- I can define gravity.
23)A force of attraction between two objects due to their mass.
24)Two objects are pulled towards each other due to their masses interacting.
FI8- I can explain the relationship between mass and gravity.
25)The more mass there is the more gravity there is.
FI9- I can list noncontact forces.
26)Gravity, Magnetism, and Electricity
FI10- I can explain how noncontact forces operate.
27)Two objects with mass attract one another because of their mass. A book and the Earth.
28)Magnetism works by two magnetic fields interacting based on direction of electron flow. Magnet sticking to an opposite pole of another magnet.
29)Electricity works by interaction of charged particles with the purpose of achieving electric neutral state. Two like charges repel.
