stationary or moving at constant speed because the acceleration is 0.
If they cancel, then their magnitudes must be equal.
No. When two forces act in the same direction, they can be added together. It is only when two identical forces act in opposite directions that they cancel each other out.
Forces that cancel each other out are said to be balanced.
The forces are said to be in equilibrium in that case.
False
When two forces cancel each other out, -- their magnitudes (size) must be exactly equal -- their directions must be exactly opposite.
unbalanced forces
False
Cancel
False
Cancel
they are called balanced forces and don't do anything except cancel each other out
