Does a change in motion occur only if a net force is exerted on an object?
No. Changes in motion can occur in other ways. A change in motion can occur if that object exerts a net force on another object, like another ball on a billiard table. The object could also bump into an immovable object and its motion would change.
What happens to the penwhat could have caused the pen's motion?
A change in velocity - for example, a motion when there was no previous motion - occurs if an unbalanced force is applied to an object.
How can you tell the wires of a toaster have high Resistance?
They get red-hot, but the fuse does not blow, nor the breaker trip. Lower resistance wire fed with 120 volts might draw enormous current and get red hot, but the fuse would blow, or the breaker trip. Of course, You could always whip out your trusty multimeter and measure the resistance (allowing for change with temperature rise of course). Or, you could measure the voltage, then the current, then divide voltage by current to get resistance (at operating temperature).
How can free fall motion and circular motion both be classified as acceleration?
Answer #1:Free fall is motion due to gravity.centripetal force causes the acceleration in a circular motion.===========================Answer #2:"Acceleration" means a change in either the speed or the direction of motion.(Or both, of course.)Maintaining a steady 30 miles per hour as you round a curve is acceleration.In the case of free fall, the speed is constantly increasing.In the case of circular moltion, the direction is constantly changing, and the speed could also be.
What is the measure of mass in motion?
According to Newton's first law, a mass will remain at rest and a mass in motion will remain in motion in a straight line at constant velocity unless acted on by an unbalanced force. So the relationship between mass and motion is that in order to change a mass's motion, you must apply an unbalanced force.
What kind of electricity is in motion?
Alternating current could fit this description.
Air in motion is called?
When Air is in motion it is called the wind. It Could also be called a breeze or wind current
What could cause an object at rest undergo change in motion?
Regardless of what the object is doing before the change, the only thing that can change its motion is force.
How does a constellation stay the same?
Actually, all the stars of a constellation are in motion. It is just that the distance between them is so great that the motion is not apparent to us. Over the course of thousands of years you could tell they change positions with respect to each other.
What is a charge in motion?
A charge in motion is usually called an electric current, but could also be called dynamic electricity (analogous to a charge at rest being called static electricity).
Does a change in motion occur only if a net force is exerted on an object?
No. Changes in motion can occur in other ways. A change in motion can occur if that object exerts a net force on another object, like another ball on a billiard table. The object could also bump into an immovable object and its motion would change.
What is any change in an object's motion called?
The change in an object's motion, is simply force.The object cannot change motion unless acted upon by an outside force. For example: If I throw a baseball, it will never stop unless acted upon by gravity (or the outside force). Or the outside force could be it smacking into a wall or your friends head.
What happens to the penwhat could have caused the pen's motion?
A change in velocity - for example, a motion when there was no previous motion - occurs if an unbalanced force is applied to an object.

Do stars change p0sition?
Yes, every star is moving. We call the actual movement of a star "proper motion", to distinguish it from the "apparent motion" of the stars rising and setting. This is because the "apparent motion" is caused by the Earth spinning and us going around with it. However, the "proper motion" of most stars is so small, and the stars themselves are so far away, that with only a few exceptions no person could notice any change over the course of a lifetime. One of the few exceptions is Bernard's Star, which is not only moving quite fast, it's also fairly close (as stars go). If you were to watch it very carefully over the course of 50 or 60 years, you might be able to notice the change in position.

What would cause scientist to change the current model of the atom?
they could discover a new atom and it would change
