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.
No, constant velocity means there is no change in velocity over time. Impulse is the change in momentum, given by the force applied over a period of time. Momentum is mass times velocity, a vector quantity.
Velocity decreases on a constant impulse, as impulse is equal to the change in momentum. When a force is applied for a certain amount of time, it results in a change in momentum which causes the velocity to decrease at a constant rate.
To find impulse with velocity and mass, you can use the formula: Impulse mass x change in velocity. This means that the impulse is equal to the mass of an object multiplied by the change in its velocity. By calculating the product of the mass and the change in velocity, you can determine the impulse experienced by the object.
To calculate impulse using mass and velocity, you can use the formula: Impulse mass x change in velocity. This means that you multiply the mass of an object by the change in its velocity to determine the impulse. Impulse is a measure of the change in momentum of an object.
To find velocity using impulse and mass, you can use the formula: velocity impulse / mass. Impulse is the change in momentum, which is calculated by multiplying the force applied to an object by the time it is applied. By dividing the impulse by the mass of the object, you can determine the velocity at which the object is moving.

Velocity decreases on a constant impulse, as impulse is equal to the change in momentum. When a force is applied for a certain amount of time, it results in a change in momentum which causes the velocity to decrease at a constant rate.
The value of an impulse is the change in momentum. If the mass remains constant it is the mass times the change in velocity.

By dividing the impulse by the mass of the object, you can determine the velocity at which the object is moving.
Impulse is equal to the change in momentum of an object, which is the product of its mass and velocity. So, the greater the mass or velocity of an object, the greater the impulse required to change its momentum.
To determine velocity from impulse, you can use the formula: Impulse Force x Time Change in Momentum. By knowing the impulse and the mass of the object, you can calculate the change in momentum. Then, by dividing the change in momentum by the mass of the object, you can determine the velocity.
constant velocity
Yes, impulse is equal to the change in momentum of an object, which can be calculated as the mass of the object multiplied by the change in velocity. So, impulse is related to the change in velocity of an object.
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.
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
