# free body diagrams for four situations are shown below

There is a net force since there is an acceleration the slope on a v-t graph means acceleration. Free-body diagrams for four situations are shown below.

For each situation, determine the net force acting upon the object. Depress the mouse on the pop-up menus to view the answers. Depress mouse to view answer to Situation A.

The net force is zero Newtons. All the individual forces balance each other i. Depress mouse to view answer to Situation B. The net force is 5 Newtons, left. The vertical forces balance each other i. The leftward force friction remains unbalanced. Depress mouse to view answer to Situation C. Depress mouse to view answer to Situation D. The net force is 15 Newtons, up. The upward force of air resistance is only partially balanced by the downward force of gravity - 15 N of upward force remains unbalanced.

In a previous unit, several means of representing accelerated motion position-time and velocity-time graphs, ticker tape diagrams, velocity-time data, etc. Combine your understanding of acceleration and the newly acquired knowledge that a net force causes an acceleration to determine whether or not a net force exists in the following situations.
