A+B together allows us to make the impact force internal (and not appear in the linear impulse-momentum equation). FBDs for A and B individually allows us to determine the t-direction components of ...

Stupid lava sticks! To figure out what's happening when objects collide, we'll have to take into account two main qualities: momentum and impulse. We'll also discuss what physicists mean when they ...

Segment 4A: Momentum and Impulse We define the terms momentum and impulse. Segment 4A: Momentum and Impulse We define the terms momentum and impulse. We see the impulse-momentum theorem in action ...

When two objects collide the total momentum before the collision is equal to the total momentum after the collision (in the absence of external forces). This is the law of conservation of momentum.
