12/17- Final Review Day 2

Front

What is energy?

Back

The ability to cause motion or to allow something to move.

Front

How can you create electricity using a voltmeter?

Back

Move the magnet back and forth.

Front

What is one advantage of electromagnets?

Back

They can be switched on or off.

Front

What is the total mechanical energy of an object?

Back

Kinetic energy plus the potential energy of the object at any instant during its motion.

Front

What factors affect the potential energy of a magnet in the presence of another magnet?

Back

How close the magnets are together and which direction the poles point.

Front

Define kinetic energy.

Back

The energy an object possesses due to its motion.

Front

What is potential energy?

Back

The energy stored in an object due to its position or configuration.

Front

Explain the relationship between kinetic and potential energy in a pendulum.

Back

As the pendulum swings, kinetic energy is highest at the lowest point, while potential energy is highest at the highest points.

Front

What is an electromagnet?

Back

A type of magnet in which the magnetic field is produced by an electric current.

Front

How does the strength of an electromagnet change?

Back

It can be increased by increasing the current or adding more coils.
