Place the carts in the desired configuration. Magnets face each other for elastic collisions. Velcro sides face each other for completely inelastic collisions. A magnet side faces a velcro side for ...

Coronal mass ejections (CMEs), emissions of magnetized ionized gas from the Sun, can damage satellites and communication technology, so being able to predict where they are heading and how much energy ...

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. It ...
