Calculating Speed Review

What is speed?

• measurement of a change in an object's position over time

• distance divided by time

• How far an object moves

• how long it takes something to complete something

speed =

• speed x time

• distance ➗ time

• mass x velocity

• distance ➗ speed

Distance is...

• distance divided by time

• measurement of a change in an object's position over time

• how far an object moves

• seconds, minutes, hours, etc

Time is...

• an object's change in position relative to a reference point.

• distance divided by time

• how far an object moves

• how long it takes something to complete something

Time can be measured in...

• how far an object moves

• seconds, minutes, hours, etc

• the rate at which velocity changes (speeds up)

• an object's change in position relative to a reference point

Motion is...

• the rate at which velocity changes (speeds up)

• seconds, minutes, hours, etc

• an object's change in position relative to a reference point.

• fraction of a minute

Acceleration is...

• the rate at which velocity changes (speeds up)

• how you measure the data

• a unit of length

• fraction of a minute

Units are...

• how you measure the data

• speed x time

• how long it takes something to complete something

• an object's change in position relative to a reference point

A meter is...

• a fraction of a minute

• how you measure the data

• speed x time

• a unit of length

A second is...

• distance

• fraction of a minute

• mass x velocity

• how you measure the data
