velocity trivia questions
Velocity describes speed with what additional property?
Answer: Direction
Bonus fact: Velocity is a vector quantity.
What is the SI unit of velocity?
Answer: Meters per second
Bonus fact: Velocity has units of distance per time.
What is acceleration?
Answer: Rate of change of velocity
Bonus fact: Acceleration can change speed or direction.
What is terminal velocity?
Answer: The constant speed reached when drag balances weight
Bonus fact: At terminal velocity, net force is zero and acceleration stops.
Inertia is an object's tendency to resist changes in what?
Answer: Motion
Bonus fact: Objects resist changes in velocity.
Acceleration measures how quickly what changes?
Answer: Velocity
Bonus fact: Acceleration is the rate of change of velocity.
An object moving at constant speed in a circle is accelerating because what is changing?
Answer: Direction of velocity
Bonus fact: Changing direction means velocity changes even if speed stays constant.
An accelerometer measures what?
Answer: Acceleration
Bonus fact: Accelerometers sense changes in velocity.
Which reference frames are the natural setting for Newton's first law?
Answer: Inertial frames
Bonus fact: In inertial frames, force-free objects move at constant velocity.
Momentum depends on mass and what?
Answer: Velocity
Bonus fact: Momentum equals mass times velocity.
What is the classical formula for kinetic energy?
Answer: ½mv²
Bonus fact: Mass and the square of velocity determine kinetic energy.
Compared with a curveball, a slider is usually thrown how?
Answer: Faster
Bonus fact: Sliders typically sit between fastballs and curveballs in velocity.
