A force is a push or a pull on an object. We experience forces every day as we lift, push, or carry objects. A force is a vector quantity, which means it has both a magnitude and a direction. In the SI system of units, force is measured in units of newtons, abbreviated N. (One newton is a little less than one-quarter pound.) For example, if you hold an apple in your hand, you exert a force with a magnitude of about 1 newton, directed upward.   Forces are vector quantities, which means they have which of the following? a. Magnitude only  b. Direction only       c. Both magnitude and direction   A 20 N force is acts on a rock. From the information given, we know which of these? a. Both the magnitude and direction of the force on the rock b. The magnitude of the force on the rock       c. The direction of the force on the rock   While kicking a ball, a kicker's foot applies an 80 N force to the ball at an angle of
