force - push or pull that causes an object to move, stop, or change direction​, In physics​ - a force is anything that makes an object accelerate​, If an object is stationary, - it won’t start moving without a force.​, Forces come in - pairs, Forces have - a magnitude and a direction, SI unit for force is - the Newton​, We use a spring scale - to measure force.​, Net Force - The overall force acting on an object after all forces are combined.​, Forces in the same direction - we add them.​, Forces in opposite directions - you subtract them.​, Balanced Forces: - The forces in each direction are “equal” and do not cause a change in motion​, Unbalanced Forces​: - If the multiple forces acting at one time are not balanced out (equal), then acceleration can/will occur on the object - change in motion, When unbalanced forces act in opposite directions - you can find the net force​, An unbalanced force always causes - a change in motion​, Magnitude - The difference between the two forces​, Direction - Direction of the largest force​, Multiple forces - can combine to move an object that has too much inertia for one force alone., If forces are not equal and are acting in opposite directions, - a negative acceleration can/will occur.,
