5 µC negative charge sitting in an electric field moves away from the source charge. The electric potential difference of the moving charge is measured as 1J/C. How much work or energy was added to the system to get the charge to move.

The force will determine the acceleration.

Anika asks eva to roll a basketball and then a bowling ball to her. which requires more force to roll, and why?

Gravity is pulling an object into the sun. the closer the object gets to the sun, the greater the gravitational force that acts on the object, increasing its acceleration. a line graph plotting the speed of the object against time would have which shape? a: straight line of positive slope b: curved line that slopes upward c: curved line that slopes downward d: straight line of negative slope
