Which of the following best illustrated an application of Newton's First Law (also called the Law of Inertia)?

• A passenger not wearing a seatbelt is ejected from an automobile during a severe crash.

• Dinner plates remain on a table when a slick table cloth is pulled out from underneath them.

• An ice hockey puck continues sliding across the relatively frictionless ice until it comes into contact with a wall or player's stick.

• All of these are examples of Newton's First Law.

When the car suddenly stops, the objects in the back seat are thrown forward. This explains . . .

• Newton's First Law of motion- Inertia

• Newton's Second Law of Motion

  Mass times Acceleration

• Newton's Third Law of motion:

  action-reaction.

• Gravity and Friction

Which type of heat transfer play the largest role in the changing height of the hot air balloon?

• Convection, because as the heat from the flame is increased, less dense air fills

  and lifts the balloon

• Conduction, because as the heat from the flame is increased, heat can move into

  the balloon without traveling through particles

• Condensation, because as the heat from the flame is decreased, water droplets

  form on the sides of the balloon, making it heavier

• Radiation, because as the heat from the flame is decreased, the flow of energy is

  able to pull the balloon down

A cup of tea sat in a

cool science classroom over a 30-minute time period. Which of the following best explains the flow of thermal energy in relationship to the temperature of the tea and surrounding air?

• The thermal energy of the tea moved from inside the cup to the surrounding air.

• The thermal energy of the cool classroom moved from the room into the tea.

• Condensed water vapor from the air formed around the rim of the cup, which then

  transferred thermal energy into the tea.

• Evaporation of the tea resulted in less tea in the cup, which decreased the amount

  of thermal energy in the cup.
