If a bicycle wheel rotates 100 times, how does this affect the distance traveled compared to if it rotated only 50 times?

• A) The bicycle will travel the same distance

• B) The bicycle will travel half as far

• C) The bicycle will travel twice as far

• D) The bicycle will travel four times as far

What is directly proportional to the distance a bicycle travels?

• A) The radius of the wheels

• B) The number of wheel rotations

• C) The gear settings

• D) The pedal size

What is the usual scale marking on a protractor for measuring angles in degrees?

• Radians

• Degrees

• Centimeters

• Meters

How is a complete revolution measured in radians?

• pi radians

• 2 pi radians

• pi divided by 2 radians

• 4 pi radians

What is angular velocity?

• A measure of how fast an object moves from point to point

• A measure of how fast an object rotates through an angle

• The time it takes for an object to complete one rotation

• The distance an object travels in one rotation

What does the Greek letter omega (ω) with an overbar represent in the context of angular velocity?

• Average speed

• Average displacement

• Average angular velocity

• Average acceleration

What does angular acceleration represent in the context of a car's motion?

• The change in the car's speed over time

• The change in angular velocity of the car's wheels divided by the time required to make that change

• The total distance traveled by the car

• The constant speed of the car

How is average angular acceleration calculated according to the image?

• α = Δω * Δt

• α = Δω / Δt

• α = Δt / Δω

• α = ω / t

What does a bicycle's linear motion depend on?

• The weight of the bicycle

• The rotational motion of its wheels

• The color of the bicycle

• The type of terrain
