#### Part A: Introduction(00:54)

FREE PREVIEW

Acceleration is the rate at which the speed of a moving object alters over time. Speed changes can be quantified with mathematics.

#### Part B: Faster and Faster(05:00)

The formula for acceleration is change of velocity divided by time taken. The delta in the equation represents the change in a quantity. See examples of both acceleration and deceleration.

#### Part C: Acceleration Due to Gravity(11:37)

Speed increases as an object falls at a rate of 9.8 meters per second every second. Watch as Spiro Liacos perform experiments with balls, a ticker tape machine, and feathers to demonstrate how air resistance and weight impacts acceleration. Objects reach terminal velocity at 200 km/hr.

#### Part D: "g"s(05:29)

One "g" refers to a rate of 9.8 meters per second per second every second. Liacos provides examples of converting accelerations to "g"'s. Relative motion will be explored in the next episode.

### Description

In episode 2, we introduce students to the concept that acceleration is a measure of how quickly something changes its speed. We join James Bond as he falls out of an aeroplane without a parachute, splash into the water at 50.4 km/hr with presenter Spiro Liacos, and watch on helplessly as a truck runs off an unfinished bridge and explodes in a massive fireball.
