Which family on the periodic table is known for its strong magnetic properties?
What is Rare Earth Elements?
What is the largest electromagnet that we know of?
What is Earth?
What is mass and what unit do we use to measure it?
What is the amount of matter in an object and Kilograms (Kg) or grams (g)?
What are four common forces that act on objects?
What is applied force, gravity, friction, magnetism (or electromagnetism)?
Explain the Law of Inertia.
What is, It states that an object in motion will stay in motion and an object at rest will remain at rest unless acted on by an external force?
What is a magnet that is NATURALLY magnetic and always magnetic called?
What is a permanent magnet?
What the properties of electromagnets? (Hint there are 4 or 5)
What is they are temporary, they have a soft iron core, you can change the poles, you can easily demagnetize them by switching off the electrical current, you can change the strength of the magnet by changing the strength of the current.
What is speed?
What is the distance an object travels over a unit of time?
Which force is always acting on every object?
What is gravity?
Explain the Law of Mass and Acceleration and its formula.
What is, it states that the net force on a body is equal to the mass multiplied by the acceleration and F=MA?
What are the three properties of magnets?
What is Strength Property, Directive Property, and Repulsive Property?
Name 5 common uses for electromagnets.
What is velocity?
What is the speed in a given direction?
What is the unit of force and how do we abbreviate it?
What is Newtons (N)?
Explain the Law of he Law of Action and Reaction.
What is, it states that for every action there is always an equal and opposite reaction?
Explain the Repulsive Property.
What is the Repulsive Property states that the same poles of magnets repel each other?
Explain how to make an electromagnet?
What is, add an electrical current to something with a soft iron core?
What is acceleration?
What is the change in velocity?
What is the net force of a basketball player who jumps with 10N, gravity is 8N?
(Must draw diagram for credit)
What is 2N?
What is 648N?
Explain what a magnet and poles are.
What is a magnet is a material or object that produces a magnetic field and the pole of a magnet is the region where the external magnetic field is the strongest at each end of a magnet.
Explain how are electromagnets different from permanent magnets?
What is electromagnets are temporary, the strength of electromagnets can be changed, you can switch the poles of electromagnets.
