Electric, Magnetic, and Gravitational Field Review

Front

What is the relationship between electric charges that attract each other?

Back

Both charges must be different (one positive and one negative).

Front

What factors affect the gravitational force between two objects?

Back

The gravitational force depends on the mass of the objects and the distance between them.

Front

What happens to gravitational force when the distance between two objects increases?

Back

The gravitational force decreases.

Front

What is the effect of like charges on each other?

Back

Like charges (both positive or both negative) repel each other.

Front

What is the effect of opposite charges on each other?

Back

Opposite charges (one positive and one negative) attract each other.

Front

How does mass affect weight on different planets?

Back

Weight is the force of gravity acting on an object's mass; it varies with the planet's mass.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity on that mass.

Front

Where are magnetic fields strongest in a magnet?

Back

Magnetic fields are strongest at the poles of the magnet.

Front

What is a gravitational field?

Back

A gravitational field is a region around a mass where other masses experience a force of attraction.

Front

What is an electric field?

Back

An electric field is a region around a charged object where other charges experience a force.
