Physics II Lesson 23: Physics of Vehicles Flashcard

Front

What is the role of friction between car wheels and the road?

Back

Friction is necessary to both start the car moving and to stop the car.

Front

Which vehicle is likely to have the most traction?

Back

A bus is likely to have the most traction due to its larger surface area and weight.

Front

Where is potential energy stored in a rubber band powered car before it is released?

Back

Potential energy is stored in the rubber band.

Front

What is a drawback of too much friction between car tires and the road?

Back

Cars have worse fuel efficiency due to excessive friction.

Front

How can you tell if a rubber band powered car does not have enough traction?

Back

The wheels would peel out while the car doesn't move much.

Front

Define traction in the context of vehicles.

Back

Traction is the grip between the vehicle's tires and the road surface, allowing for movement and control.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as a stretched rubber band.

Front

Explain the relationship between friction and control in vehicles.

Back

More friction generally provides better control, but too much friction can lead to decreased efficiency.

Front

What factors affect the amount of traction a vehicle has?

Back

Factors include the weight of the vehicle, the type of tires, and the surface of the road.

Front

What happens to a car's speed when there is too little friction?

Back

The car may skid or slide, making it difficult to control speed and direction.
