Once a current is set in motion what can change it's course?
Coriolis effect
If an object in motion will stay in motion what causes a bullet shot into fall?
its the laws of motion. once a thing like the bullet has lost its force, it will stop moving and slowly go down its the laws of motion. once a thing like the bullet has lost its force, it will stop moving and slowly go down
Can an object be in motion if no external forces are acting on it?
yes. external forces ALTER an object's motion... but once it starts moving and has no external forces being applied on it, it will go in a straight line with constant velocity (Newton's 1st Law of Motion)
What describes a perpetual motion machine?
A motor that requires no energy input once it is running
What is the different between linear motion and circular motion?
Linear motion is motion in a straight line, such as a dragster heading down the track, or a person walking down the sidewalk. Circular motion is motion in a circle, such as a yo-yo swung around someones head, or a car making a turn. In physics, while these two categories of motion exist, in most cases outside textbook examples, an objects motion will include both types of motion at once.

Coriolis effect
How does force affect an object's motion?
When a force is acted on an object the motion changes. Newtons 2nd law of motion states: An object in motion will stay in motion, and an object out of motion will stay out of motion, unless met with an unbalanced force. If a force is aplied to an object in motion it either accelerates, or it will stop once met with sed unbalanced force.
Why is it more difficult to push a stalled car from rest to keep it in motion once it has started to run?
Force = mass X acceleration. When you start pushing a stationary 'dead weight' you are making it go faster than it was or accelerating it. Once the car is moving at a steady speed, it is no longer being accelerated. The greater the mass or inertia of an object the more it will resist changes in its motion. (See Newton's Laws of Motion.)
Does a dynamic character remains the same during the course of the story?
A dynamic character changes at least once. A static character doesn't change at all.
What is varistor?
A varistor is a variable resistor. It changes value dependent on the current draw and operates by changing its value as the resistor's temperature changes. For instance, during turn-on of a device, the resistor heats up causing the resistor to change it's value, thereby limiting the inrush current to the device. Once the initial start-up current is reduced and the device is operating normally, the resistor cools down and changes value again.
How did the mayflowers captain stay on course?
He didn't stay on course, but was blown off course by a storm. The Mayflower was to land in Virginia but ended up in Massachusetts. The ships of the time used a astrolabe, compass, and there is a strong ocean current that runs from Europe to the east coast of the United States. Once a ship gets into that current it will virtually carry the ship to the North American coast.
What causes you to keep moving once you are in motion?
momentum
Why is it easier to push a car once it is already in motion?
It is already in motion and therefore needs less force.
How is the full load current different to the starting current- is the full load current higher or lower than the starting current?
While starting a motor from standstill to its rated speed, the motor has to overcome the inertia and generate enough torque to over come it. In the process the motor takes higher current during the starting. Once started and set in motion the current reduces ti its normal value. Full load current is lower than the starting current normally.
Would there have to be an Unbalanced force acting on moving object?
There would have to be an unbalanced force put an object in motion but once in motion no force is necessary for it to remain in motion
If an object in motion will stay in motion what causes a bullet shot into fall?
its the laws of motion. once a thing like the bullet has lost its force, it will stop moving and slowly go down its the laws of motion. once a thing like the bullet has lost its force, it will stop moving and slowly go down
Why does a dc motor develop a high current when starting?
the mechanical force needed to start the motor (move one pole to another) is greater at rest. once forward motion is developed it is easier for one pole to get to the next
