Two irregular objects a and b carry charges of opposite sign. the above figure shows the electric field lines near each of these objects.
the charge of a is positive while the charge of b is negative, and the electric field is stronger closer to a.
the charge of a is positive while the charge of b is negative, and the electric field is stronger closer to b.
the charge of b is positive while the charge of a is negative, and the electric field is stronger closer to a.
the charge of b is positive while the charge of a is negative, and the electric field is stronger closer to b.

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
