Diagram showing the resultant forces on three different objects
Calculate the magnitude and direction of the resultant force in the diagram below.
Step 1: Add up all of the forces directed to the right
4 N + 8 N = 12 N
Step 2: Subtract the forces on the right from the forces on the left
14 N – 12 N = 2 N
Step 3: Evaluate the direction of the resultant force
Step 4: State the magnitude and direction of the resultant force
The force which opposes the motion of an object
Friction is a force which opposes an objects motion, acting in the opposite direction to it
When calculating resultant forces, always remember to provide units for your answer and to state whether the force is to the left, to the right, or maybe up or downAlways provide your final answer as a description of the magnitude and the direction, for example:
