The Mystery of the Skidding Car Flashcard

Front

What is the speed of Emily’s car when it started skidding?

Back

55 mph

Front

Define skidding in the context of vehicle dynamics.

Back

Skidding occurs when a vehicle loses traction with the road surface, causing it to slide uncontrollably.

Front

What factors can contribute to a car skidding?

Back

Factors include wet or icy roads, sudden braking, sharp turns, and high speeds.

Front

Explain the concept of friction and its role in skidding.

Back

Friction is the force that resists the motion of two surfaces sliding against each other. Insufficient friction can lead to skidding.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

How does speed affect the stopping distance of a vehicle?

Back

Higher speeds increase stopping distance due to greater momentum and the time required to react.

Front

What is the relationship between mass and momentum in a skidding car?

Back

Momentum is the product of mass and velocity. A heavier car at the same speed has more momentum, making it harder to stop.

Front

Define the term 'braking distance'.

Back

Braking distance is the distance a vehicle travels from the point where brakes are applied to when it comes to a complete stop.

Front

What is the effect of road conditions on vehicle skidding?

Back

Poor road conditions, such as rain, ice, or gravel, can significantly reduce traction and increase the likelihood of skidding.

Front

Explain the concept of 'reaction time' in driving.

Back

Reaction time is the time it takes for a driver to respond to a stimulus, such as seeing a hazard, which affects stopping distance.
