If constant motion means constant velocity then,
total distance / total time = avg velocity => avg speed
constant velocity => avg velocity = velocity
The constant acceleration
An object is said to be in uniform motion if it moves in a straight line at constant speed.
Judge by the distance it has moved in relation to another object.
An object is said to be in uniform motion when it goes in a constant straight line. Motion is the part of the mechanics branch of physics.
It is a measure of the component of the velocity of the object in the direction towards or away from the reference point (the origin). It takes no account of the object's velocity in the transverse direction. It is, therefore, not a measure of the object's speed or velocity. For example, the distance of an object going around in a circle about the origin is a constant. So the slope of the distance vs time graph will be 0. But the speed of the object is NOT 0 (nor is its velocity 0).
You divide the distance by the time.You divide the distance by the time.You divide the distance by the time.You divide the distance by the time.
The constant acceleration
the object is on uniform motion
If the motion is truly in the form of a circle, the phrase uniform circular motion describes it appropriately. This means that the object is in a constant state of motion about a fixed point at a constant distance from that point. Circular motion can be considered an acceleration, because an acceleration describes any change in velocity or direction. Since circular motion involves constant change in direction, the object exhibits constant acceleration.
Seems to me that either of the following could settle that issue: Necessary and sufficient: -- The object is in motion AND there exists a point from which the distance to the object is constant. Sufficient but not necessary: -- The component of the object's position that is parallel to some straight line is proportional to the cosine of (time + a constant).
determine if the momentum of an object moving in a circular path at constant speed is constant.
A Reference Point A reference point is needed to determine if an object is in motion.
A reference point must be chosen to determine the motion of an object.
A Reference Point A reference point is needed to determine if an object is in motion.
are constant
A distance-time graph for an object moving at a constant velocity will be a straight line - the gradient of the line corresponds to the velocity. Non-uniform motion will cause the gradient of the line to change.
A Reference Point A reference point is needed to determine if an object is in motion.
