Forces Vocab

Front

Net Force

Back

Total force from adding all forces acting on an object in each direction.

Front

Gravity: A force attracting all matter in the universe to each other, stronger with more mass, weaker with distance.

Back

A force attracting all matter in the universe to each other, stronger with more mass, weaker with distance.

Front

Weight:

Back

The force of gravity on an object. Equal to mass times gravity's strength.

Front

Force: an expression of energy causing motion change if unbalanced. Has size & direction.

Back

an expression of energy causing motion change if unbalanced. Has size & direction.

Front

Acceleration: a change in an object’s speed, motion, or velocity.

Back

Acceleration: a change in an object’s speed, motion, or velocity.

Front

Normal Force: A motion from pushing on a surface, always acts perpendicular to the force created.

Back

A motion from pushing on a surface, always acts perpendicular to the force created.

Front

Mass:

Back

A measure of how much matter is in an object and how much it resists acceleration.

Front

Friction: A force that slows objects down, acting opposite to motion.

Back

A force that acts to slow objects down. Always acts in the direction opposite of motion.

Front

Balanced Forces: When multiple forces are in balance and add up to 0 in a given direction, causing no change in motion.

Back

When multiple forces are in balance and add up to 0 in a given direction, causing no change in motion.

Front

Reaction Forces:

Back

The force that automatically occurs when a force acts on an object in the opposite direction and the same amount.
