question

1. the sum of all forces acting on an object is known as.
2. which of the following is a characteristic of a balanced force?
3. which of the following is a characteristic of an unbalanced force?
4. which of the following represents balanced forces?

choice a
applied force purple
choice b
et force black
choice c
normal force green
choice a
equal in size, opposite in direction red
choice b
causes a change in the direction of an object sky blue
choice c
causes a change in the motion of an object orange
choice a
equal in size, opposite in direction sky blue
choice b
does not cause a change in the motion of an object green
choice c
causes a change in the motion of an object purple

Explanation:

1. The sum of all forces acting on an object is the net - force by definition.
2. Balanced forces are equal in size and opposite in direction, resulting in no change in the object's motion.
3. Unbalanced forces cause a change in the motion of an object.
4. When forces are equal in magnitude and opposite in direction (like two 7N forces in opposite directions), they are balanced forces.

Answer:

1. B. net force
2. A. equal in size, opposite in direction
3. C. causes a change in the motion of an object
4. The pair of 7N forces in opposite directions represents balanced forces.
