I have no idea why you don't do any work when you carry an object at constant velocity. In a vehicle, you would have rolling resistance and wind resistance. On any other surface, you would have friction. Of course, once you put the object into motion, the energy required to keep it in motion would be less than that required to get it there.
Even if you put something into orbit the orbit would slowly decay according to the gravitational section of the Theory of Relativity.
What else can I help you with?
Why dont you do work when you carry an object at a constant velocity?
When you carry an object at a constant velocity, there is no net displacement in the direction of the force applied. Work is defined as force x distance x cos(theta), and since the displacement is zero in this case, the work done is also zero.
A change in a moving object's direction always results in a change in its?
velocity. When an object changes direction, its velocity vector changes, even if the object's speed remains constant. This change in velocity can be caused by forces such as gravity or friction acting on the object.
How do you calculate momentum?
Momentum = mass x velocity. Using standard terminology, p = mv. Δp = m v - m0 v0 (Change in mass = mass x velocity - initial mass x initial velocity ) If your mass stays the same, this can be simplified to Δp = m ( v - v0 )
Why is weight not constant?
Weight is not constant because it depends on the gravitational pull acting on an object. Weight is a force that results from the mass of an object interacting with the gravity of the planet it is on. Therefore, if the gravitational pull changes, the weight of an object will also change.
When a car rounds a corner going at constant speed is its acceleration is zero?
No, even if a car is moving at a constant speed while rounding a corner, it is still undergoing centripetal acceleration towards the center of the curve. This acceleration is responsible for changing the direction of the car's velocity.

why dont you draw the velocity of triangles?
What is uniform velocity?
A body is said to move with uniform velocity if it has no acceleration. This implies that the body moves with a constant speed along a straight line path. This also means that the body moves with equal displacements in equal intervals of time, however small these time intervals may be.

I Dont know sombody help me on this an I'm on a quiz (:
Can an object be moving and still be in equilibrium?
Yes, an object can be moving and still be in equilibrium if the forces acting on it are balanced. This can occur when the object is moving at a constant velocity in a straight line with no net force acting on it.
