Kinetic Energy
What is the energy of an object in motion called?
Kinetic Energy
What type of energy is stored in an object due to its position?
potential energy
What are the two types of magnetic poles?
north and south poles
What do magnetic field lines represent?
The direction and strength of a magnetic field.
How can you do quiz or test retakes?
Have no missing work for the unit, And email Ms.W when done
How does the mass of an object affect its kinetic energy?
The kinetic energy increases with the mass of the object.
A book is on a shelf 2 meters high. If the book has a mass of 2 kg, what is its potential energy? (Use the formula on the board)
39.2 Joules
What happens when like magnetic poles are brought together?
They repel each other.
How can you tell the strength of a magnetic field from its field lines?
The closer the lines are together, the stronger the magnetic field
How long do you have to turn in latework?
Until the end of the next unit or the end of the quarter whichever comes first
If a car travels at a speed of 10 m/s and has a mass of 1000 kg, what is its kinetic energy? (Use the formula on the board)
50,000 Joules
How is gravitational potential energy related to height?
Gravitational potential energy increases as height increases
How do opposite magnetic poles interact?
They attract each other.
What is the shape of the magnetic field around a bar magnet?
The field lines spread out from the north pole and return to the south pole, forming closed loops.
How can you find paper copies of missing work?
The orange folder at the front
If the speed of an object doubles, how does its kinetic energy change?
It quadruples
Describe a scenario where potential energy is converted into kinetic energy.
When a roller coaster drops from a height, its potential energy converts into kinetic energy as it descends.
What is a real-life example of magnetic pole reactions?
The attraction or repulsion between magnets on a refrigerator.
How can magnetic field lines be visualized?
By using iron filings or a magnetic compass to show the direction of the field.
Do you still need to make up anywork you missed while out?
yes
Explain how kinetic energy can be transformed during a collision.
Kinetic energy can be transferred to another object or converted to other forms of energy, such as heat or sound.
What is the relationship between potential energy and the distance between interacting objects?
Potential energy depends on the relative positions of objects; as they move closer or farther apart, potential energy changes.
Explain how magnetic poles relate to electric charges.
Just as like charges repel and opposite charges attract, like magnetic poles repel and opposite magnetic poles attract.
Describe how magnetic field lines change when two magnets are brought close together.
The field lines will show attraction or repulsion based on the poles facing each other, with lines bending accordingly.
When does Ms.W grade all latework?
