Front

What is a magnetic field?

Back

A region around a magnet in which you can measure magnetic forces.

Front

What happens when two magnets are brought close together?

Back

They can either attract or repel each other depending on their poles.

Front

What occurs when a charged object comes into contact with an uncharged object?

Back

The charged object can transfer electrons to the uncharged object, giving it a charge.

Front

How is electricity produced in a generator?

Back

By changing mechanical energy into electrical energy.

Front

What determines the strength of gravitational attraction between two objects?

Back

The mass of the objects and the distance between them.

Front

What is the force that pushes two magnets away from each other called?

Back

Repulsion.

Front

What is the result of an object gaining electrons?

Back

The object becomes negatively charged.

Front

What is the result of an object losing electrons?

Back

The object becomes positively charged.

Front

What type of energy is converted in a generator?

Back

Mechanical energy is converted into electrical energy.

Front

What is the relationship between distance and gravitational force?

Back

Gravitational force decreases as the distance between two objects increases.
