What is the SI unit for frequency?

Back

The SI unit for frequency is seconds^-1, also known as Hertz (Hz).

Front

What does the slope of a position vs. time graph represent?

Back

The slope of a position vs. time graph represents velocity.

Front

Which equation is used to analyze velocity changes over a distance when time is not known?

Back

Front

What does the area under a velocity vs. time graph represent?

Back

The area under a velocity vs. time graph represents displacement.

Front

If X and Y have a linear relationship, what happens to Y if X is tripled?

Back

If X is tripled, Y will be multiplied by three.

Front

Define frequency in the context of motion.

Back

Frequency is the number of occurrences of a repeating event per unit of time, often measured in revolutions per second.

Front

What is the relationship between velocity and acceleration?

Back

Acceleration is the rate of change of velocity with respect to time.

Front

What does a flat line on a position vs. time graph indicate?

Back

A flat line on a position vs. time graph indicates that the object is at rest.

Front

How do you calculate average velocity?

Back

Front

What is the significance of the y-intercept in a velocity vs. time graph?

Back

The y-intercept represents the initial velocity of the object.
