Chapter 5- The Physics of Driving

2. What are the factors affecting energy of motion?

The factors that affect your energy of motion are speed and weight. The energy of motion increases proportionally with the increase in weight, and the energy increases proportionally with the square of the increase in speed.

1. How does gravity affect your vehicle?

The force of gravity will cause your vehicle to speed up when going downhill, and slow down when going uphill.

4. What three things can reduce traction?

This is just a list of things that can reduce traction: bald tires, worn shock absorbers, low tire pressure, or a change in roadway conditions such as snow, ice or rain.

3. How does traction control your vehicle?

Traction enables your tires to grip to the road and control your vehicle. Without traction, your car would not be able to accelerate, stop, or turn.
