What has to be true about an object for it to have kinetic energy?

• it must be moving

• it must be elevated

• it must be experiencing a net force

• it must be accelerating

What is potential energy?

• the energy an object has due to its position or condition
• the energy an object has due to its motions
• the energy an object has due to its chemical composition
• theh energy an object has due to its atomic structure

When does an object have no kinetic energy?

• when it is at rest
• when it is moving very slowly
• when the only force that is acting on it is gravity
• when it has no electrical charge
