Consider the following statements. I. Objects with large amounts of charge have bigger electric fields than do objects with small amounts of charge; II. Electrons have a positive charge; III. Like charges repel. Which statement(s) is/are true? 1. None is true. 2. I only 3. II and III only 4. I and II only 5. I and III only 6. III only 7. All are true. 8. II only

the independent variable, or the one that is intentionally manipulated is the speed.

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.

mass:

note: to earn full marks when solving science word problems, you must show your work:

formula.

example:

given values:

mass = 0.3 kg.

force tends to be low and long diustance masses are high

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
