What else can I help you with?
Do most objects travel in a constant speed?
No, most objects do not travel at a constant speed. Factors such as forces acting upon the object, changes in direction, and external factors can cause objects to speed up, slow down, or change direction. Objects can also have variable speeds due to changes in energy or motion.
To justify with calculation average speed is equal to instantaneous speed?
Average speed is calculated by dividing the total distance traveled by the total time taken. Instantaneous speed, on the other hand, is the speed at a specific moment in time. They can be equal in situations where speed is constant over time, but in most cases, they will differ because instantaneous speed can vary as the object moves.
Is electricity as fast as light?
No, electricity does not travel at the speed of light. The speed at which electricity travels depends on the medium it is passing through. In most cases, electricity travels at a fraction of the speed of light.
What is a possible state of an object in the absence of net force?
When no net force acts on an object, then its velocity is constant. That means that its speed and direction don't change. If it is at rest, its velocity is zero. If it is in motion, then it continues in a straight line at constant speed. The most general statement is: When net force acts on an object, then the object accelerates. When no net force acts on an object, then its acceleration is zero. Even more general than that: A = F/M . (An object's acceleration) is (the net force acting on it) divided by (its mass).
Which would you expect to produce the most centrifugal force?
An object rotating at a high speed or a heavier object rotating at a slower speed would produce the most centrifugal force. The centrifugal force depends on the mass of the object and the square of the rotational speed.

Space probes can travel millions of miles without using any fuel?
Newton's Second Law: The force applied to an object is proportional to its mass and its acceleration. What this means is that any object, traveling in a straight line, at a constant speed, requires no force to maintain that motion. Most notably, in space, where there is no air resistance to slow the object down, no engines would be required to travel, except to change speed and course.

Why do most people incorrectly think that it takes a constant force to produce a constant speed of a moving object?
because they take air resistance into consideration, if you pushed something along in space it would carry on and wouldn't stop

How do you find the most probable speed?
V_mp (most probable speed) = sqrt(2KT/m) where K is the Boltzmann constant
Which would you expect to produce the most centrifugal force?
An object rotating at a high speed or a heavier object rotating at a slower speed would produce the most centrifugal force. The centrifugal force depends on the mass of the object and the square of the rotational speed.
Would an object shrink when traveling at the speed of light?
The object would probably disintegrate completely. The speed of light is 299,792,458 meters per second, that's fast enough to circle the globe at least 6 times. The force against the wind would have to be at least 500,000 pounds of pressure, and that's an underestimation. The object would most likely catch fire, as well.
Why most of the object move in a straight line?
Objects will continue to move in a straight line unless acted upon by an external force. This is known as Newton's First Law of Motion. When no other forces are present to change an object's motion, it will continue moving in a straight line at a constant speed.
Which situation is most likely to show a constant rate of change?
The distance traveled by a truck driving at a constant speed compared with time.
Is it possible to have a changing velocity and a constant speed?
Yes, the velocity of a constantly (or not constantly) accelerated object will vary. Velocity is distance per unit time with a vector. It's speed (distance per unit of time) in a given direction. Under constant acceleration, the velocity is changing at a constant rate. But the velocity is changing. It is varying. The object could be speeding up or it could be slowing down. Or it could be changing direction. Any of these change velocity. An object that is experiencing constant acceleration will have its velocity varying. Why wouldn't it have?
