Usually several forces act on an object. If the net force of all these forces (using vector addition to add them correctly) is not zero, then the object will move. If the net force is zero then it won't move. However, even if the net force is zero the forces will generally cause internal stress and may deform the object. So a single force acting on an object always causes motion (acceleration) because you would have a non zero net force. If two equal and opposite forces pulled on your arms the net force would be zero and you would not move, but the internal stress on your body could be quite painful.

What do unbalanced forces always cause in motion?

Do all forces always cause motion?

-- First of all, motion doesn't require any force.-- If the forces on an object are unbalanced, then the object's motion changes. Always.-- If the forces on an object are balanced, then the object's motion doesn't change.


Do forces always rsult in motion?

No, forces do not always result in motion. A force can cause an object to start moving, change its direction, or change its speed. However, if the forces acting on an object are balanced, the object will remain at rest or in constant motion.


Which forces always cause a change in motion?

The forces that always cause a change in motion are unbalanced forces. When there is an imbalance of forces acting on an object, it will accelerate or decelerate, causing a change in its motion. Balanced forces, on the other hand, do not cause a change in motion as they cancel each other out.


What is the name for forces that cause a change in the motion of an object?

The name for forces that cause a change in the motion of an object is "external forces." These forces can include friction, gravity, air resistance, and applied forces.


What can other forces do that frictional forces cannot do?

cause motion &+ cause positive acceleration . #


What do forces opposing motion cause?

Friction


What are forces that do not cancel out or change an objects motion?

Some forces that do not cancel out or change an object's motion include net external forces, such as applied forces, frictional forces, and gravitational forces. These forces can cause changes in an object's motion, such as accelerating or decelerating it.


Do balanced forces cause motion?

No. An unbalanced force causes motion, but balanced forces keep a body in motion in a straight line at constant velocity, or at rest at constant 0 velocity.


Can you always detect motion when paired forces are in action?

No.


What forces can cause change in motion?

unbalanced force


What is a charge in motion called?

These forces that cause a change in motion are called Unbalanced Forces, therefore forces that never cause a change in motion and stay the same are called Balanced Forces.
