An object might change its velocity by accelerating, decelerating, changing direction, or a combination of these. For example, if a car starts from rest and accelerates along a straight road, it would experience a change in velocity. Another example is a ball thrown upwards experiencing a change in velocity as it goes up and then down due to the acceleration of gravity.
What else can I help you with?
What path might an object take that involves changing its velocity?
An object might follow a curved path or change direction to alter its velocity. This could happen due to external forces like gravity, friction, or applied forces. The object could accelerate, decelerate, or change direction to adjust its velocity.
When a cart is changing direction is it acceleration?
Consider a graph paper with Axis X and Y. Cart travel in X direction but suddenly, the cart change direction and so it must reduce velocity on X and increase velocity on Y. Net velocity might be the same but small acceleration and deceleration is apply in 2 dimension motion.
Which characteristic of motion could change without changing the velocity?
Well, we know that velocity describes the speed and direction of motion, so you can't change either of those. We don't usually think of 'position' as a characteristic of motion, but if we try hard to please you, then we might observe that the position changes while velocity remains constant.
When you know both the speed and direction of an object's while it is in motion do you know the acceleration of the object?
Not necessarily. Knowing an object's speed and direction of motion does not automatically provide information about its acceleration, which is the rate of change of velocity. Acceleration depends on how much the velocity is changing over time, which might not be evident just from knowing the initial speed and direction.
The speed and direction of a moving object determines the what of an object?
You might be referring to velocity. It is a vector physical quantity and both speed AND direction are required to define it. One can also consider velocity as the rate at which an object changes position.

What would happen to an object's velocity if no work was being done on the object?
The velocity might still change, in the case of a force applied at a right angle to the movement. In this case, since the object's direction changes, its velocity changes.

What is constant speed?
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.

When is the instantaneous velocity equal to avg velocity?
Mainly, when the velocity doesn't change. Also, in the case of varying velocity, the instantaneous velocity might, for a brief instant, be equal to the average velocity.
How is it possible to be accelerating at a constant speed?
Since acceleration involves a change in velocity, and object might be accelerating even though its speed is constant.
What would happen to an objects's velocity if no work was being done on the object?
If no work is being done on an object, its velocity would remain constant, assuming no external forces are acting on it. According to Newton's first law of motion, an object at rest stays at rest and an object in motion continues moving at a constant velocity unless acted upon by an external force.
What is the definition of the constant speed?
Constant speed is a fixed rate of displacement of an object. Constant velocity is a fixed rate of displacement in a fixed direction. That might not make sense, but let's dig in a bit and see if we can make sense of it. Consider a truck on an open freeway and a horse on a merry-go-round. If both the truck and the horse move a fixed distance per unit of time, they are moving at a constant speed. Speed is displacement per unit of time. In the case of the truck, it might be convenient to measure it in miles per hour or kilometers per hour. The horse might be moving at a speed measured in feet per second or metres per second.Velocity is similar to speed, but it includes a directionvector. An object might be moving at a constant speed and a constant velocity, but another might be moving at a constant speed but not at a constant velocity. The only difference might be that the latter object is constantly changing direction. Recall the truck on the freeway from the above example. It might be moving at 60 miles per hour east, and that defines its speed and direction, or its velocity. The horse, however, is constantly changing direction. Its speed might be constant at, say, 6 feet per second or 2 metres per second, but it is moving in a circle and is constantly changing direction. Its velocity will, therefore, be constantly changing as well.
