Science Module 4 EOM

Electric Force

• It can only attract objects that are in direct contact.

• It can cause objects to attract or repel each other and can act over a distance.

• It is only effective in a vacuum.

• It is a type of magnetic force that requires a medium.

Attract

• Objects pulling toward each other

• Objects pushing away from each other

• Objects remaining stationary

• Objects moving in a circular path

Force

• A push or a pull that makes an object move or stop

• A type of energy that can be stored

• A measure of the mass of an object

• A unit of measurement for distance

Consistent

• Always the same

• Occasionally different

• Rarely the same

• Infrequently changing

Pull

• A force that moves an object toward you

• A force that pushes an object away from you

• A type of energy used in machines

• A method of lifting heavy objects

Contact force

• A force that touches an object

• A force that acts at a distance

• A force that is always in motion

• A force that cannot be measured

Investigation

• A process to gather information about a subject

• A method to create new theories

• A way to entertain oneself

• A technique to avoid learning

Repel

• Objects attracting each other

• Objects pushing away from each other

• Objects remaining stationary

• Objects merging into one another

Exert

• To apply a force

• To withdraw from a situation

• To observe carefully

• To create a barrier

Magnetic Force

• The force exerted by a magnet that can cause it to attract objects made from certain kinds of metal and attract or repel other magnets

• A force that only repels objects made of metal

• A type of force that only works in a vacuum

• A force that can only attract non-metal objects
