Understanding Speed and Velocity

What is the term used to describe the speed of an object at a specific moment in time?

• Variable speed

• Constant speed

• Average speed

• Instantaneous speed

How does adding direction to speed change its classification?

• It becomes momentum

• It becomes acceleration

• It becomes force

• It becomes velocity

How is average speed calculated?

• Total distance multiplied by total time

• Instantaneous speed divided by time

• Total time divided by total distance

• Total distance divided by total time

What is the key difference between average speed and instantaneous speed?

• Instantaneous speed is calculated using total distance

• Average speed is over a period of time

• Instantaneous speed is always higher

• Average speed includes direction

What historical problem did Newton solve that relates to instantaneous speed?

• The problem of calculating instantaneous speed

• The problem of gravity

• The problem of motion

• The problem of energy conservation

What mathematical method is used to find instantaneous speed?

• Calculus

• Algebra

• Geometry

• Trigonometry

In uniform motion, how does average speed relate to instantaneous speed?

• They are unrelated

• Instantaneous speed is always greater

• They are equal

• Average speed is always greater

What is the formula for instantaneous speed using calculus?

• Total distance divided by total time

• Limit of change in distance over change in time as time approaches zero

• Total time divided by total distance

• Change in distance divided by change in time

What does the slope of a distance-time graph represent in non-uniform motion?

• Average speed

• Total time

• Instantaneous speed

• Total distance

In non-uniform motion, what tool is used to determine instantaneous speed?

• A calculator

• A ruler

• A graph

• A stopwatch
