Can a particale accelerate if its speed is canstant?
No, a particle cannot accelerate if its speed is constant. Acceleration is the rate of change of velocity, and if the speed (magnitude of velocity) remains constant, then the acceleration is zero.
If a car moves with a constant speed does it also moves with a constant velocity?
Not necessarily.Speed is a scalar measurement that only measures magnitude.Velocity, on the other hand, is a vector measurement and adds the important distinction of a direction.A car rounding a curve may be going the same speed, but its velocity is constantly changing throughout the curve because its direction keeps changing.
Does light accelerate?
Light does not accelerate in the traditional sense, as it always travels at a constant speed of approximately 299,792 kilometers per second in a vacuum. This speed is a fundamental constant in physics known as the speed of light.
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?
Can an object accelerate and have a constant speed at the same time?
No, an object cannot accelerate and have a constant speed at the same time. Acceleration is a change in velocity, which includes speed or direction. If an object has a constant speed, it means there is no acceleration occurring.

Before entering a curve you need to?
You may need to slow down as you are entering a curve, then accelerate to resume a safe speed as you are leaving the curve.
Does an object accelerate if it moves in a straight line at constant speed?
no
Can a body have constant speed and still be accelerating give example?
Yes. The simplest example is an object moving at a constant speed in a circle.

What is the best way to drive around a curve?
Close to the inside. As you head into the corner, break slightly (depending on your speed) and then at the middle of the curve, accelerate out of the curve.
Can an object accelerate and have a constant speed at the same time?
No, an object cannot accelerate and have a constant speed at the same time. Acceleration is a change in velocity, which includes speed or direction. If an object has a constant speed, it means there is no acceleration occurring.
A situation in which you can accelerate even though you speed does not change?
"Acceleration" means a change of speed or direction of motion, or both.If you change direction ... like turning a corner ... then there is acceleration,even though your speed is constant.Anything traveling on a circular track, even at a constant speed, has constantacceleration.
Compare the tension of a train with constant speed and acceleration?
Unless the train is in a curve, you cannot have constant speed and constant acceleration. You either have constant speed and zero acceleration, or you have changing speed and constant acceleration. Please restate the question.
How can a car accelerate if its speed is constant?
A car can accelerate even if its speed is constant by changing its direction or increasing its velocity. For example, if a car is moving in a circle, it is constantly changing its direction, resulting in acceleration. Additionally, if a car is moving at a constant speed and then speeds up, it is also accelerating.
