Module 3: Laws of Nature

Module Three

TOPIC ONE: Laws of Nature

Open Ended

Tell me one funny story about how one of the laws of nature (gravity, kinetic energy, momentum, or inertia) has affected you.

Poll

Will you be driving a top heavy vehicle?

• Sedan or Hatchback

• SUV

• Truck

Multiple Choice

The white truck and the dump truck are traveling at the same speed. Which vehicle has more momentum and why?

• They both have the same forward momentum.

• The dump truck because it is heavier.

• The white truck because it is faster.

Multiple Choice

How is inertia affecting the position of the person driving the vehicle around the hairpin turn?

• Pushing the weight of the car back

• Pushing the weight of the car forward

• Pushing the weight of the car right

• Pushing the weight of the car left

Multiple Choice

What is being demonstrated in the graphic?

• Forward pitch

• Backward pitch

Multiple Select

Three Factors that Factor in Creating Vehicle Roll:

• Color of the vehicle

• Grade of the road

• Manual or automatic transmission

• Steering wheel movement

• Brake application

Multiple Choice

If you are driving and the back end of your vehicle starts to slide right or left, what is the safest counter maneuver to maintain control of your vehicle?

• Brake hard and hold the steering wheel so the front wheels are straight.

• Let go of the wheel and take your feet off the pedals.

• Turn the steering wheel in the direction of the skid and slowly decelerate.

Multiple Choice

This is the natural force that constantly pulls all things to the earth and affects an object’s weight.

• Center of gravity

• Gravity

• Inertia

• Momentum

Multiple Choice

The point where the mass of the vehicle is concentrated and balanced.

• Center of gravity

• Gravity

• Inertia

• Momentum

Multiple Choice

The higher the center of gravity, the more unstable the vehicle becomes.

• True

• False

Multiple Choice

Refers to the quantity of motion an object has.

• Center of gravity

• Gravity

• Momentum

• Inertia

Multiple Choice

An object’s tendency to resist any change in its state of motion.

• Center of gravity

• Gravity

• Momentum

• Inertia
