Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.
Which of the following is/are required to fully explain force?
a) strength
b) direction
c) area
d) both a and b
Which of the following is caused by force?
a) slow down the body
b) change the direction of the body
c) speed up the body

What is the SI (system international) unit of force?
a) pascal
b) ohm
c) newton
