force diagrams Flashcards
what is a force diagram
A diagram that shows the forces acting on an object
what are forces used to represent
the forces
what does it mean if two arrows pointing in opposite direction are the same size
the forces are balanced
when an object has balanced forces what does this mean
it means the object is either stationary or moving at a steady speed in one direction
what does it mean if two arrows pointing in an opposite direction are different sizes
forces are unbalanced
when an object has unbalanced forces, what does this mean
the object will either accelerate or decelerate
how do you find the overall force when they are acting in opposite directions
subtract the forces
how do you find the overall when forces are acting in the same direction
add the forces
