Net force is the sum of all forces acting on an object.
True
False
An object with balanced forces acting on it will accelerate.
True
False
The resultant vector represents the total effect of two or more vectors.
True
False
The slope of a distance vs. time graph represents speed/velocity.
True
False
A constant velocity means both speed and direction remain unchanged.
True
False
Acceleration can only occur when an object speeds up.
True
False
If two forces act in opposite directions, the net force is found by adding them.
True
False
A time vs. distance graph with a straight horizontal line indicates the object is at rest.
