What conclusion can you draw about the acceleration is it constant increasing decresing or zero?
Depending on the situation, acceleration can be any of those.
When the velocity of a particle is constant its acceleration is also constant?
Its acceleration is zero, which is constant
Should acceleration be constant?
Acceleration must be constant to use kinematic equations. Acceleration need not be constant if working with energy.
What is the difference between constant speed and constant acceleration?
Constant speed means that speed doesn't change. Constant acceleration means that acceleration doesn't change. (If the acceleration is anything but zero, speed WILL change.)
What would be the situation if mass were added to or lost from a system while a constant force was being applied to the system?
Since Force = Mass x Acceleration If force is held constant and one varies the mass then the acceleration will vary according to the equation: Acceleration = Force / Mass As a result, the acceleration is inversely proportional to the mass of the object. In other words, if one increases the mass of the object, the acceleration of the object will decrease proportionally. Similarly, if one decreases the mass of the object, the acceleration will increase proportionally.

How does force vary with acceleration at constant mass?
If acceleration is kept constant but you vary the mass, the force will vary in direct proportion to the mass. If the mass increases, the force will also increase, and if the mass decreases the force will also decrease. Newton's 2nd Law, illustrated by the equation F=ma, illustrates this.
When the velocity of a particle is constant its acceleration is also constant?
Its acceleration is zero, which is constant
What is your acceleration if you have a constant velocity?
If your velocity is constant, then your acceleration is zero.
How are constant force is related to mass and acceleration?
Force = (mass) times (acceleration) Constant force produces constant acceleration.
Should acceleration be constant?
Acceleration must be constant to use kinematic equations. Acceleration need not be constant if working with energy.
What is acceleration of a rain drop that falls at a constant velocity?
If the velocity is constant then there is no acceleration. The acceleration is zero.
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.
What is the difference between constant speed and constant acceleration?
Constant speed means that speed doesn't change. Constant acceleration means that acceleration doesn't change. (If the acceleration is anything but zero, speed WILL change.)
How are constant speed and constant acceleration different?
There is a huge difference between constant speed and constant acceleration. Constant speed is when the object is travelling constant, no change in its velocity and acceleration or in other words no extra force to speed up. Constant acceleration when the object is acceleration constant, it means that the speed of the object is change at the same rate each second. The acceleration rate at which the object is travelling is constant. for example, when a car is stationary at a traffic light and it starts acceleration, picking up speed but the rate of acceleration will not constant because the amount of force applied differs each second due to the acceleration rate.
Is it possible to achieve a constant acceleration?
Yes - for a while. Or indefinitely, if you will accept zero acceleration as "constant acceleration".
Can something have both a constant velocity and constant acceleration?
No it cannot. It is either one or the other. For constant velocity, acceleration must be 0, meaning there is no acceleration happening here. If there is constant acceleration, then the velocity is constantly changing.
