1. Record: Select the BAR CHART tab, select Acceleration from the dropdown menu, and turn on Show numerical values. The bar on the left shows the magnitude of the acceleration, or lal. The units of
acceleration are meters per second per second, or m/s2. What is the current magnitude of the
acceleration?

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
