Motion of the Center of Mass

Mr. Andersen explains the concept of center of mass using weebles as an example. He discusses how the center of mass affects motion and equilibrium, and provides practical examples with objects like hammers and bicycles. The video also covers methods to find the center of mass in different objects and how to calculate motion, velocity, and acceleration using this concept.

What characteristic of weebles allows them to wobble without falling over?

• Low center of mass

• Lightweight material

• High center of mass

• Uniform shape

Why is it important to know the center of mass when analyzing the motion of a bicycle?

• To measure the height of the bicycle

• To ignore internal forces and focus on external forces

• To determine the color of the bicycle

• To calculate the weight of the bicycle

What happens to the center of mass when a hammer is thrown?

• It follows a predictable path

• It remains stationary

• It follows a random path

• It moves in a straight line

How can the center of mass be found for an irregular object?

• By performing a hang test

• By measuring its weight

• By calculating its volume

• By using a formula

If an object moves 12 meters in 3 seconds, what is its velocity?

• 6 meters per second

• 5 meters per second

• 4 meters per second

• 3 meters per second
