An object is in motion only if its distance from a reference point is?
An object is in motion only if its distance from a reference point is changing. The average speed of the object is given by the object's rate of change of displacement from the reference point over time.
How is the center of the gravity determined when an object is at rest or in motion?
If the object is a thin lamina with uniform thickness (e.g. a piece of paper), the the centre of gravity of the object is at its geometrical centre. It can be determined by suspending a load (e.g. pendulum) on an edge of the lamina twice and the point where the plumb lines intersect is the centre of gravity.
How do you recognize motion?
Deciding if an object is moving isn't as easy as it sounds. We can only discern relative motion and we have to use reference points. (A reference point is an object that is not moving that you compare to the other object.) An object is in motion when it's distance from the reference point is changing.For example, you could say that you and this computer are not moving. Other than your eyes blinking, chest pumping up and down, and you clicking on the mouse, you and this computer are not in motion. Since the distance between you and the computer is not changing, you can conclude that neither you or the computer are moving.
When an object moves at speeds that are close to that of light its length will?
Not change, from the frame of reference of the object, that being more or less the whole point of special relativity.From the point of view of an outside observer, it will contract along the direction of motion.
In what way is the motion of a freely falling object different from the motion of the cart?
motion of free falling object does not have friction, while motion of the cart has force of friction
What is a stationary object by which motion can be determined?
frame of reference
What point must be chosen to determine the motion of an object?
A reference point must be chosen to determine the motion of an object.
What is needed to determine whether in object is in motion?
A Reference Point A reference point is needed to determine if an object is in motion.
Is needed to determine whether an object is in motion?
A Reference Point A reference point is needed to determine if an object is in motion.
What is the point from which motion can be determined?
i believe it is momentum
When is an object in motion considered to be a point object?
when the object is at rest
An object is in motion only if its distance from a reference point is?
An object is in motion only if its distance from a reference point is changing. The average speed of the object is given by the object's rate of change of displacement from the reference point over time.
What is needed to determine whether an object is in motion?
A Reference Point A reference point is needed to determine if an object is in motion.
When an object changes position over time relative to a reference point the object is?
motion
How is the center of the gravity determined when an object is at rest or in motion?
If the object is a thin lamina with uniform thickness (e.g. a piece of paper), the the centre of gravity of the object is at its geometrical centre. It can be determined by suspending a load (e.g. pendulum) on an edge of the lamina twice and the point where the plumb lines intersect is the centre of gravity.
How far an object is from a reference point?
the answer to that is motion
What is the comparison of an object's motion over time to another object?
Motion it the change of an object over time relative to its reference point. that is called a reference point.
