Motion: Acceleration

The video tutorial explains the concept of acceleration as the rate of change in velocity, using examples like sports cars and motorcycles. It introduces the formula for calculating acceleration and demonstrates its application through a snowboarder example. The tutorial also covers graphing acceleration to visualize changes over time.

What is acceleration primarily concerned with?

• The distance an object travels

• The rate of change in velocity

• The weight of an object

• The time it takes to stop

Which of the following is the correct formula for calculating acceleration?

• Initial velocity minus final velocity divided by time

• Final velocity plus initial velocity divided by time

• Final velocity minus initial velocity divided by time

• Initial velocity times final velocity divided by time

In the snowboarder example, what was the snowboarder's initial velocity?

• 2 meters per second

• 1.5 meters per second

• 3 meters per second

• 0.5 meters per second

How long did it take for the snowboarder to reach the bottom of the half pipe?

• 1.5 seconds

• 2.0 seconds

• 2.3 seconds

• 3.5 seconds

What is the snowboarder's acceleration in the example provided?

• 0.65 meters per second squared

• 0.95 meters per second squared

• 0.85 meters per second squared

• 0.75 meters per second squared
