When we draw an electric field, what do the lines that we draw mean?
They show the direction a positively charged object would accelerate if placed at that point
When we draw magnetic field lines, the arrow drawn points in the direction of
the north pole of a test compass.
Electric force is measured in units of
Electric force and charge are ________________ related and electric force and distance are ________________ related.
The "G" in Newton's Law of Universal Gravitation is a very small number. Because G is a small number, the force of gravity is a _____ force.
Two masses are labeled A and B. A is 1.0 kg and B is 2.0 kg. A and B are 1.0 meters apart. What is the gravitational force?
The gravitational forces of A and B are the same
Two masses attract each other with a gravitational force of 1600 N.a If the masses are moved four times farther apart, what will the gravitational force between them be? d=4
Distance is inversely related, so d squared 4x4= 16 so then f = 1600/16
If the mass on one object doubles, the gravity would...
If the distance between objects doubles, the force of gravity would
be 4x weaker because of d squared
Two masses are labeled A and B. A is 1.0 kg and B is 2.0 kg. A and B are 1.0 meters apart.
