Distance = rate x time. Rate as in speed.
The object is stationary as its velocity is zero. The velocity of an object is the gradient of its distance-time graph and as the graph is a horizontal straight line, its gradient is zero. The object is stationary also as its distance from the time axis is not increasing.
acceleration
false \
It is constant in magnitude. It is changing in direction.
Photon or rather light
If the distance is not changing, the object is not moving. If the distance is increasing or decreasing linearly then the object is moving at a constant velocity. If the distance is increasing or decreasing parabolically then the object is being accelerated or decellerated.
In the case of constant speed: distance = speed x time For variable speed: speed = ds/dt, where "s" is the object's position.
a "body" "moving body" an "object" is moving with constant velocity. [OR] a "body" is moving with constant velocity.
A straight line with a constant slope
determine if the momentum of an object moving in a circular path at constant speed is constant.
determine if the momentum of an object moving in a circular path at constant speed is constant.
The condition for an object to stay at rest or if moving, moving at a constant velocity is that the sum of forces acting on the object be zero or that no force acts on the object.

Constant speed is movement at a fixed (constant) distance per unit of time. The same amount of distance is covered by the object in the same amount of time at each measurement of that same interval. An example of an object moving at a constant speed might be an object in orbit. Something up their above the drag of the atmosphere will move at a constant speed, and will continuously move around the earth at the same speed. Note that velocity is speed with a direction vector. An object in orbit will have a constant speed, but its velocity will be constantly changing because it is constantly changing the direction it is moving.
