Science EOC List 1

Forces and Motion

TermDefinition
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.
