A 0.156 kg ice puck collides with a 0.170 kg ice puck. both were originally moving at the same speed. which one has the larger c
hange in velocity? they both have the same change in velocity. the 0.156 kg puck changes velocity the most. they both have no change in velocity. the 0.170 kg puck changes velocity the most.
<span>When the two pucks collide, momentum will still be same but it acts in two different directions.
Momentum formula goes like this M = m x v, m is mass and v is speed. That means velocity is inversely proportional to mass.
So the puck with less weight changes the most, so the 0.156 kg puck changes velocity the most

When a light beam travels from one medium to another, then it's velocity decreases or increases depending upon the optical density of the other medium.
When a light beam enters another medium at an slanting angle the ray that reaches the medium first changes it's velocity before any other ray, the change in velocity causes the beam to bend.
Electric fields are produced by two kinds of charges, positive and negative. Magnetic fields are associated with two magnetic poles, north and south, although they are also produced by charges
