Segments in this Video

Part A: Introduction (00:54)


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.

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.
