Answer:
Unbalanced forces are not equal, and they always cause the motion of an object to change the speed and/or direction that it is moving.
Step-by-step explanation:
When two unbalanced forces are exerted in opposite directions, their combined force is equal to the difference between the two forces.
The magnitude and direction of the net force affects the resulting motion
This combined force is exerted in the direction of the larger force
For example, if two students push on opposite sides of a box sitting on the floor, the student on the left pushes with less force (small arrow) on the box than the student on the right side of the box (long arrow).
The resulting action (net force: smaller arrow to the right of the = shows that the box will change its motion in the direction of the greater force
If unbalanced forces are exerted in the same direction, the resulting force (net force) will be the sum of the forces in the direction the forces are applied.
When forces act in the same direction, their forces are added. When forces act in opposite directions, their forces are subtracted from each other.
Unbalanced forces also cause a nonmoving object to change its motion
If there is no net force acting on the object, the motion does not change. If there is a net force acting on an object, the speed of the object will change in the direction of the net force.
