# Speed and Velocity Song

## Science Songs

Spend a moment and just take a look all around you

People, dogs, and plants, everything it constantly moves

Even still objects, like buildings or lamp in your room

They’re still in motion because our planet is always moving

Speed is the distance an object moves in time

Like the speedometer when your car drives

Meters per second is the SI

The standard for the measurement

Equation, average speed equals distance over time

It’s scalar, magnitude, no measure of direction

Instantaneous speed is the speed of an object at a specific

Moment in time, but it may speed up or slow, measured in meters per second

Speed is only scalar, it doesn’t tell us which way we drive

Calculated by measure distance divided by time

Like if you drove to your grandma’s house just to say hi

You’d take the meters, divide it by the full time to drive

Speed equals distance over time

Speed equals distance over time

Speed equals distance over time

Speed equals distance over time

Now velocity is how fast moving with direction

A numerical value, vector with two measurements

Like you’re driving 10 meters per second going west

The direction and distance is called the displacement

Say if you were walking to class

But displacement is the shortest distance

From the starting to the ending

Equation, equals displacement over the time

Instantaneous velocity split second in time

Acceleration is a measure of how fast the

velocity of an object changes

It’s also a vector using size and direction

Let’s say you walk to the store it takes you 30 seconds

Walking west 100 meters, it is the full distance

But the displacement it only shows 50 meters so it’s

Your velocity’s 1.7 meters per second

velocity equals displacement over time

velocity equals displacement over time

velocity equals displacement over time

velocity equals displacement over time
