Intro to Fields/Noncontact Forces

More mass = more potential energy. More height =

• more kinetic energy.

• more potential energy.

• less potential energy.

• no effect on energy.

A potential energy that is a built-up imbalance electric charge known as static electricity (lightning, dry air, rubbing carpet/balloons), in which opposite charges attract and like charges repel is

• gravitational potential energy.

• nuclear potential energy.

• electrostatic potential energy.

• magnetic potential energy.

How are objects affected by distance with electrical, magnetic, and gravitational forces?

• As distances increases, the force increases.

• As distance decreases, the force decreases.

• As distance increases, the force decreases.

• Distance does not affect the forces.
