Summary:

• Momentum of an object depends on its velocity and its weight (mass).
• To stop an object with a large momentum requires either a large force applied quickly or a small force applied more slowly.
• When an impact occurs quickly it can be visually jarring since the force of impact is big.
• Squash and stretch is often used to soften the impact in a way that appears natural.
