Force Diagrams
-
- Force diagrams show which forces are acting on an object in specific directions. You can deduce if the forces are balanced or unbalanced.
- E.g. book on a table
- If the forces are balanced on moving object it carries on moving in the same direction with a steady speed
- E.g. an accelerating car
The orange arrow = driving force of 1500N which makes the car same directionmove forward
The yellow arrow= same directionopposite frictional force of 500N
Unequal sized arrows = unbalanced forces = car accelerates in direction of orange arrow.
- If in a force diagram the forces are acting on the same line (forward and backwards OR up and down), adding and subtracting forces gives you the overall force.
- This helps you to see if an object is: accelerating, decelerating or staying at steady speed.
- Forces acting in opposite directions = subtract
- Forces acting in same direction= add
