Want this question answered?
When you (or an object) travel without changing speed, then you have constant velocity (speed). This means there is no change in speed (acceleration) when you (or an object) is traveling.
No. An object is accelerating if it is changing speed or direction of travel. Since the person in question is running at a constant speed in a straight line, they are not accelerating.
Such an object is said to travel at a constant speed. If it doesn't change direction, it is also said to travel at constant velocity.
Any path that changes direction. To keep the speed constant and change the velocity it would have to travel in a circle or something similar.
In order for an object to travel with constant velocity the sum of forces acting on it must be zero

Constant velocity has speed always constant along the direction with respect to time. Variable velocity changes its speed with respect to time. Constant velocity has zero acceleration. Variable velocity has non-zero acceleration . An object moving at a constant velocity maintains both the same speed and direction. An object moving at a variable velocity can be changing speed or direction of travel or both.
no
Of course, since velocity is a vector quantity and speed is a scalar quantity, velocity has something speed does not: direction. Thus, an object can travel at the same speed by has a changing direction of movement, and therefore a changing velocity. For instance, a ball on a string moving in a circle at the same speed is constantly changing its velocity, which results in its path of motion.Yes. Velocity is (speed and direction of motion). If direction changes, then velocitychanges, even if speed is constant.Examples:-- Car going around a curve at a constant speed has changing velocity.-- Anything traveling a circular path at a constant speed has changing velocity.
You're fishing for "balanced", but that still doesn't make the statement true.An object on a curved path can have constant speed even though the forceson it are not balanced.

When its speed changes, when it turns changing its direction of travel or when both occur.
