Electric, Magnetic, and Gravitational Field Review

Front

What is a gravitational field?

Back

A region around a mass where another mass experiences a force of attraction.

Front

What causes the planets to orbit the Sun?

Back

The gravitational pull of the Sun combined with the inertia of the planets.

Front

What is a magnetic field?

Back

A region around a magnet where magnetic forces can be detected.

Front

What happens when two like magnetic poles are brought close together?

Back

They repel each other.

Front

What is the relationship between electric charge and electric fields?

Back

Electric charges create electric fields that exert forces on other charges.

Front

What is the formula for gravitational force?

Back

F = G * (m1 * m2) / r^2, where F is the force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.

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 acting on that mass.

Front

What is the role of Earth's magnetic field?

Back

It protects the planet from solar wind and cosmic radiation.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the effect of distance on gravitational force?

Back

Gravitational force decreases as the distance between two masses increases.
