Amplify Magnetic Fields Pre-Assessment

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration. It can be converted into kinetic energy when the object moves.

Front

How does moving a magnet affect potential energy?

Back

Moving a magnet closer to another magnet that cannot move increases the potential energy of the system if it moves against the magnetic force.

Front

What happens to kinetic energy when speed decreases?

Back

When speed decreases, kinetic energy also decreases, as kinetic energy is directly related to the speed of an object.

Front

What is the relationship between magnetic force and movement of magnets?

Back

Magnetic force can either attract or repel magnets, affecting their movement based on their relative positions.

Front

What occurs when two magnets are brought close together?

Back

Depending on their orientation, they may either attract each other (if opposite poles are near) or repel each other (if like poles are near).

Front

What is the formula for kinetic energy?

Back

Kinetic energy (KE) is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the effect of distance on potential energy in a magnetic field?

Back

As the distance between two magnets increases, the potential energy in the magnetic field decreases.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is magnetic force?

Back

Magnetic force is the attraction or repulsion that arises between electrically charged particles due to their motion.

Front

What happens to potential energy when a magnet moves in the direction of the magnetic force?

Back

The potential energy decreases when a magnet moves in the direction of the magnetic force.
