If the velocity is constant does that mean that there is no impulse?

Not necessarily. Impulse Fdt=change in momentum which could be written as mdv (constant mass, velocity changing) or dmv (changing mass, constant velocity - the so-called conveyor belt problem. Imagine a hopper filled with (say) coal is feeding the coal on to a conveyor belt. The mass of the belt increases with time, so a force has to be applied to it to keep it moving at constant velocity.

If the velocity is constant does that mean that the impulse is the momentum?
impulse = change in momentum so, no
What does mean the velocity remains constant?
there is no acceleration if the body is moving with constant velocity
If the velocity is constant does that mean that there is no change in momentum?
yes
What does it mean for an object to have constant velocity?
It means that the object moves in a straight line at a constant speed.
What is the velocity in which the body covers equal displacements in equal intervals of ttime?
In that case, the velocity is said to be constant.
If the velocity is constant does that mean that the impulse is the momentum?
impulse = change in momentum so, no
How can you find the value of the impulse?
The value of an impulse is the change in momentum. If the mass remains constant it is the mass times the change in velocity.

there is no acceleration if the body is moving with constant velocity
If the velocity is constant does that mean that there is no change in momentum?
yes
How are momentum and impulse related?
Momentum is mass * constant velocity, impulse involves imposing a force (either for or against) for a specified time , altering the velocity (and therefore, momentum)>Example. a 10 kg mass (m) @ 10 metres / second, has an impulse of 100 newtons / 10 seconds (t) applied in the direction of motion.Find the velocity change / new velocity / initial and final momentum>From f = m * a, but a = velocity change (vc) / time (t)So>f = m * (vc / t)Then>vc = t * (f / m) = 10 * 10 = 100 metres / sec velocity change (+ in this case)so, velocity is now 10 + 100 = 110 metres / sec (constant velocity)>initial momentum (p) = 10 * 10 = 100momentum (after impulse) (p) = 10 * 110 = 1100>Alternatively, to calculate final velocity after impulseFirst, find acceleration rate from a = f / myou know the impulse time, you know the initial velocity.>Use v = u + (a*t)v = 10 + (10 * 10)v = 110 metres per second
What does cv in cv boots or joint mean?
constant velocity
What does it mean for an object to have constant velocity?
It means that the object moves in a straight line at a constant speed.
What is root mean square velocity?
For an object moving at a variable velocity you:calculate the square of the velocityfind its mean valuecalculate its square root.If the velocity is constant then the RMS velocity has the same value.
Can constant velocity be zero?
Yes. Zero velocity is a velocity; if it is always zero then it is a constant velocity.
Can a moving object have impulse in itself?
yes moving objects have impulse
What is the velocity in which the body covers equal displacements in equal intervals of ttime?
In that case, the velocity is said to be constant.
How can impulse increase?
Impulse is denoted as a change in momentum. Momentum has the units of kilogram meter per second. Which is mass times velocity. So you can decrease the time and increase the velocity to increase the impulse.
