Gravity bends forward motion into an orbit.
Interactive teaching model • relationships are controlled; scale, distance or timing may be simplified and are labeled here.
The big idea
Rotation is spinning around an axis; revolution is traveling around another object.
A body can do both at once, as Earth rotates daily while revolving around the Sun yearly.

HOW SCIENTISTS KNOW
Time-lapse imaging and repeated position measurements reveal both motions.

!A COMMON WRONG MODEL
Rotation and Revolution is only a name or picture to memorize.
✓REBUILD IT WITH EVIDENCE
Connect rotation and revolution to the observable relationship, evidence and system described in the lesson.
A scientifically true sentence can still create a false picture. This repair makes the relationship visible.
Take learning into real life
Try it together
Make a motion test with a safe ball, a ramp made from a book and tape marks. Change only one variable, measure the result and name the force involved. Connect what you notice to rotation and revolution using rotation and revolution.

Three things to remember
✓Rotation is spinning around an axis; revolution is traveling around another object.
✓A body can do both at once, as Earth rotates daily while revolving around the Sun yearly.
✓Evidence matters: time-lapse imaging and repeated position measurements reveal both motions.
