Forces are also considered vectors, because the direction is important.

measured in Newtons (N) (about the weight of an apple)

a force exerted on an object causes it's velocity to change; therefore, force causes acceleration

Magnitude:

harder the push = great the effect

Direction:

Right = right

Left = left

F: a vector, representing size and direction

F: represents only magnitude

Two forces can act on each other. The sums of the two forces acting on each other are called the net force. The net force can be an unbalanced force. An unbalanced force is a force that changes an object's motion, or causes it to accelerate.

If one force is stronger than the other then they will not balance out to zero net force.

You can have two forces acting in different directions, when this occurs they cancel each other out, causing no net force.

Motion:

a change in position of an object with respect to time

motion is described in terms of velocity, acceleration, displacement, and time.
