Is impulse a vector quantity?
Two reasons. Recall impulse is the change in momentum. First the momentum is a vector. So imagine a triangle. One side is the initial momentum (with one direction), the second side is the final momentum (with a potentially different direction) and the third side is the impulse (or change in momentum). The other way to look at this is in terms of what causes the change in momentum. This is how impulse is generally described. The impulse can be defined as the average force acting on the particle multiplied by the time interval over which the force acts. This is sometimes represented as the integral of the force. As force is a vector so is the impulse caused by this force.
What is the momentum conservation's principle?
After a collision,The initial momentum of a system is equal to final momentum. m1V1=m2V2
When objects collide the total initial momentum equals the total final momentum is called what?
this is called law of conservation of momentum
When object A collides with object B and bounces back its final momentum is initial momentum?
in the opposite direction of

Why is it incorrect to say that impulse equals momentum?
Impulse is the change in momentum. Therefore Impulse is only equal to momentum if the initial momentum was equal to zero. Its the same phenomenon as position and displacement. Impulse= final momentum-initial momentum= mv - mv_0= Force * Time Where m is the mass and v is the velocity.
What is the standard unit of momemtum and impulse?
The units for impulse are kg.m/s. This is because impulse= (final momentum) -(initial momentum) and the units for momentum are kg.m/s.
What does the impulse-momentum theorem state?
Impulse equals change in momentum. "Apex" The final momentum of any object (or collection of objects) must equal to its initial momentum plus any impulse imparted to the object (or collection of objects).
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 )

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
How do you find magnitude of final momentum?
Use this formula:Final momentum = (initial momentum) + (change in momentum)
How is the change in momentum calculated?
IN general change is defined as the difference of initial from the final. So change = Final - Initial. Hence change in momentum = Final momentum - initial momentum
What Does it Men To Momentum is Conserved?
When momentum is conserved, the initial momentum is equal to the final momentum.
What is the momentum conservation's principle?
After a collision,The initial momentum of a system is equal to final momentum. m1V1=m2V2
When objects collide the total initial momentum equals the total final momentum is called what?
this is called law of conservation of momentum
Explain how momentum is transferred when a golfer hits a ball with a golf club.?
The Golf ball, initially at rest, has no initial momentum. The velocity the moment before the club strikes the ball and the clubs mass multiply to get the initial momentum. The ball then gains much momentum in the direction of the clubs initial momentum. Since there golfers arm is remaining attached to the shoulder the clubs acceleration is directed towards his shoulder and the momentum is directed in a circular direction.
