Throwing a Ball in a Boat - Demonstrating Center of Mass

The video tutorial explores the physics of a ball thrown into a canoe, examining the system's behavior when the ball lands inside and outside the canoe. It explains the concept of internal and external forces, Newton's laws, and the center of mass. The tutorial includes calculations to determine the system's center of mass and demonstrates how the system behaves under different conditions, emphasizing the importance of understanding net external forces and their impact on motion.

What happens to the canoe and Mr. P when the ball is thrown to the left and lands in the canoe?

• They move to the right.

• They move to the left.

• They move in circles.

• They stay still.

Why does the system stop moving when the ball lands in the canoe?

• Because the water is too shallow.

• Because the ball is too heavy.

• Because the canoe is anchored.

• Because there is no net external force.

What is the significance of the center of mass in this scenario?

• It causes the canoe to sink.

• It determines the speed of the canoe.

• It affects the color of the canoe.

• It remains stationary relative to the planet.

What happens to the center of mass when the ball moves to the left?

• It moves to the right relative to the boat.

• It moves to the left relative to the planet.

• It stays in the same position relative to the boat.

• It disappears.

What is the effect of the ball not landing in the canoe on the system's movement?

• The system moves to the left.

• The system stops moving.

• The system moves in a random direction.

• The system moves to the right at a constant velocity.

How is the initial position of the center of mass of the system calculated?

• By measuring the distance from the canoe's edge.

• By using the masses and initial positions of all objects.

• By dividing the total mass by the number of objects.

• By adding the masses of all objects.

What is the final change in position of the center of mass of the system?

• 30 centimeters to the right.

• 30 centimeters to the left.

• 15 centimeters to the left.

• 15 centimeters to the right.
