What defines a point at which an object will not accelerate any more?
Terminal velocity defines the point at which an object will no longer accelerate. When a falling object reaches terminal velocity, it will continue to fall at a constant speed.
When A parachutist reaches it terminal speed?
The parachutist will no longer accelerate. They will just glide with constant velocity and enjoy the scenery.
Why does a car traveling at constant speed can accelerate while a car at constant velocity connot?
The question is inherantly flawed. A car traveling at a constant speed cannot accelerate, if it could it's speed would not be constant. "Constant speed" means that speed is not increasing or decreasing but remain consistent over time. For example, if you cover 10 feet during each second, your speed is constant. "Constant velocity" implies constant speed, but it has an additional constraint: you can't change your direction. If you travel constantly at 10 feet per second in a straight line, then your speed is constant and your velocity is constant. But if you travel constantly at 10 feet per second in a wiggly line (or a circle, or anything not straight), then your speed is constant but your velocity is NOT constant. If you travel at a constant speed but change direction, velocity is changed. Or if you travel in the same direction but change the speed, velocity is changed. Average speed is is easier: distance/time So, your question should read: Why can a car traveling at an average speed accelerate, but a car traveling at constant speed cannot? Or Why am I asking the wrong questions?
What happens to free-fall velocity when air resistance equals weight?
If air resistance equals the force of gravity, the object will cease to accelerate, so its velocity will remain constant.
What is an example of something that undergoes acceleration while moving at a constant speed?
Acceleration is technically defined as a change in velocity. Velocity includes both speed and direction, so one could accelerate just by turning.
What defines a point at which an object will not accelerate any more?
Terminal velocity defines the point at which an object will no longer accelerate. When a falling object reaches terminal velocity, it will continue to fall at a constant speed.
What are the conditions for an object to stay at rest to keep moving at constant velocity or the move with increasing velocity?
A body is moving at constant velocity including zero at Equilibrium Condition, No change of energy or zero force. With force a body can accelerate, move with increasing velocity.
CAN AN Object accelerate and be moving at a constant speed?
Yes, it's direction may be constantly changing which would mean it is still accelerating.
Why is an object traveling in a circular motion?
acceleration is change in velocity.. and velocity constantly changes in circular motion, as the direction constantly changes. This constant change in velocity causes the object to accelerate.
When A parachutist reaches it terminal speed?
The parachutist will no longer accelerate. They will just glide with constant velocity and enjoy the scenery.
Why is it an object can accelerate while travelling at constant speed but not at constant velocity?
Acceleration means the velocity changes. Velocity is made up of speed and a direction, so if only the direction changes, the velocity still changes, and therefore there is acceleration. The typical example is moving around in a circle.

Explaine what happens to the velocity and the acceleration of an object in fall?
An object falling from a tall building would accelerate at a rate of 9.807 m/s2 until it reached terminal velocity, at which point it would not accelerate until it impacted the ground. Its velocity would increase as it fell until reaching terminal velocity, and then 0 when it hit the ground.
What happens to free-fall velocity when air resistance equals weight?
If air resistance equals the force of gravity, the object will cease to accelerate, so its velocity will remain constant.
What is the accelerate?
Acceleration is the change in velocity with time, for linear (constant) acceleration it is calculated by: (End Speed -Start Speed)/time taken
If an object starts to accelerate?
If an object moved with constant acceleration it's velocity must ?
Are rates of change always constant?
If I understand correctly your question, the answer is definitely no.Think about the typical physical representation of the concept of "rate of change": the velocity is the rate of change of position, right? And there's no difficulty in imagining a non-constant velocity, as when you accelerate or decelerate..
