Electricity, Gravity and Magnetism

The electric force between two or more charged objects depends on which of the following quantities?

• charge and distance between the charged objects

• mass and distance between the charged objects

• charge and mass of charged objects

• quantity of charges and their masses

An electric current flows in a wire. What is one result?

• a magnetic field is created

• any nearby magnetic fields are destroyed

• nearby magnets lose their strength

• the metal of the wire cannot be affected by magnets

How are the two forces that make up electromagnetic forces related?

• both are static

• both can be positive, negative, or neutral

• both the electric and magnetic forces are caused by the motion of charged particles such as electrons

• both gravity and light are caused by the motion of charged particles such as electrons

Gravity is...

• the force of attraction between any two objects

• the force of attraction and repulsion between like and unlike poles

• any phenomenon associated with stationary or moving electrons,ions or other charged particles

• the force that attracts a body toward the center of the earth, or toward any other physical body having mass.

Where are magnets strongest at?

• The middle of the magnet

• The north side of the magnet

• The south side of the magnet

• At both poles of the magnet

Two factors that affect the magnitude of the gravitational force between two objects are...

• mass and distance

• weight and distance

• density and size

• mass and weight

Where would an astronaut weigh less on, the moon or Earth?

• The moon, since it has less mass, it would have less gravity

• The earth, since it has a greater mass,it would have more gravity

• The moon, since it has a greater mass, it would have more gravity

• The earth, since it has less mass, it would have less gravity
