|---|---|---|---|---|---|
| balanced forces | forces on a object that combine to give a
zero net force and do not change the
motion or direction of the object.
🗑
|
||||
| gravity | attractive force between two objects that
depends on the masses of the objects and
the distance between them.
🗑
|
||||
| direction | with reference to the point or region toward which it is directed
🗑
|
||||
| displacement | distance and direction of an object’s
change in position from the starting
point.
🗑
|
||||
| electrical force | the net movement of electric charges in a
single direction,
🗑
|
||||
| force | a push or pull exerted on an object.
🗑
|
||||
| friction | force that opposes the sliding motion
between two touching surfaces.
🗑
|
||||
| magnetic force | attraction or repulsion that arises between electrically charged particles because of their motion.
🗑
|
||||
| mass | amount of matter in an object.
🗑
|
||||
| motion | the action or process of moving or being moved.
🗑
|
||||
| acceleration | rate of change of velocity; can be
calculated by dividing the change in the
velocity by the time it takes the change
to occur.
🗑
|
||||
| net force | sum of the forces that are acting on an
object.
🗑
|
||||
| speed | distance an object travels per unit of
time.
🗑
|
||||
| unbalanced force | forces on a object that combine to give a
net force NOT equal to zero and changing the
motion and/or direction of the object.
🗑
|
||||
| weight | gravitational force exerted on an object.
🗑
|
||||
| mass | amount of matter in an object.
