With any vehicle, why do we need to be aware of thermodynamics?

• Because if a vehicle gets colder it runs slower.

• Because if a vehicle escapes gravity it loses gas mileage.

• Because the convection cycle affects the flow of fuel.

• Because heat build up in the brakes affects the vehicle's ability to stop.

In a crash between two vehicles. which is true of momentum?

• All momentum is lost.

• All momentum is doubled.

• Momentum transfers between the vehicles but the total is the same.

• The vehicles each keep their own momentum.

Have you ever ridden on a motorcycle?

• Never have and never will

• Never have but hope to some day

• Yes, but only as the passenger

• Yes, as the driver

How does Newton's 2nd Law of Motion apply to the movement of any vehicle?

• More force applied makes the vehicle go faster.

• It stays at rest until acted upon by an outside force.

• There is an equal and opposite reaction when you turn.

• The wheels spin acting like a gyroscope.

Which of these statements is true about a vehicle's use of energy?

• ALL vehicles use electromagnetic energy in their fuel tanks.

• Vehicles have no energy, it's just forces.

• Only radiant energy powers vehicles that people use.

• Vehicles have potential energy stored in their fuel supply which transfers into mechanical energy when the vehicle moves.

How does safety equipment protect us from crash forces?

• It displaces them to the atmosphere.

• It slows them down, but you get hit with the same total force.

• It destroys the forces.

• It absorbs and disperses the crash forces across a bigger surface area.
