acceleration trivia questions
Acceleration measures how quickly what changes?
Answer: Velocity
Bonus fact: Acceleration is the rate of change of velocity.
What is the SI unit of acceleration?
Answer: Meters per second squared
Bonus fact: Acceleration is measured in m/s².
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.
What is acceleration?
Answer: Rate of change of velocity
Bonus fact: Acceleration can change speed or direction.
If the same force acts on a larger mass, acceleration will be what?
Answer: Smaller
Bonus fact: Acceleration equals force divided by mass.
What force opposes a parachutist's downward motion?
Answer: Drag
Bonus fact: Drag from the air reduces acceleration and terminal speed.
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.
What physical quantity is a measure of an object's inertia in classical mechanics?
Answer: Mass
Bonus fact: Greater mass means greater resistance to acceleration.
Which law is summarized by F = ma?
Answer: Newton's second law
Bonus fact: Force equals mass times acceleration.
What equation summarizes Newton's second law for constant mass?
Answer: F = ma
Bonus fact: Net force equals mass times acceleration.
Near Earth's surface, gravitational potential energy is commonly calculated as what?
Answer: mgh
Bonus fact: Mass, gravitational acceleration, and height determine the energy.
A cheetah can maintain its top speed for only about what distance?
Answer: 300 yards
Bonus fact: Its sprinting anatomy delivers extreme acceleration but is physiologically costly.
