You are holding a full bowl of hot soup while standing in the kitchen. As you begin moving, some of the soup spills out of the bowl onto the floor. Upon reflection, you realize that

• the soup spilled because of air resistance.
• if you had traveled faster this wouldn't have happened.
• the soup wanted to stay where it was, but you moved the bowl.
• the soup and the bowl act as one body with the same velocity.
