What is the unit of impulse in physics?
Same as the unit of momentum - an impulse is a transfer of momentum. Velocity x mass. Or the equivalent force x time.
How do you find impulse?
The impulse of force is commonly used to calculate forces in collisions. Active formula. Impulse = Average force x time = mass x change in velocity
The impulse given to a ball with mass of 4 kg is 16 Nsec If the ball starts from rest what is its final velocity?
An impulse is simply a change of momentum, and momentum is defined as mass x velocity; so you just divide the momentum by the mass to get the velocity. Note about the units: newton x second is the same as kilogram x meter/second2.
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.
What could be described as impulse equals change in momentum?
Momentum = Mass x Velocity The change in momentum = (mass of the object x the end velocity) - (mass of the object x the beginning velocity)
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.
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.
How can find impulse with mass and velocity given?
Impluse = m x v
How is impulse relative to momentum?
impulse (force x time) is equal to momentum (mass x velocity); Ft=mv
How do you impulse?
The impulse of force is commonly used to calculate forces in collisions. Active formula. Impulse = Average force x time = mass x change in velocity

A ball with a mass M is falling on to the ground with some velocity V1 and raising with velocity V2 find the impulse?
Impulse = |change in momentum| Initial momentum = MV1 down Final momentum = MV2 up Missing momentum = impulse = M ( V1 - V2 )
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.
