Momentum

The video tutorial introduces the concept of momentum, explaining it as a product of mass and velocity. It covers how momentum is calculated and its vector nature, emphasizing its directionality. Examples from sports illustrate momentum's role in real-life scenarios. The tutorial highlights momentum's importance in physics and engineering, encouraging viewers to consider forces affecting momentum in contexts like roller coasters.

What two factors determine the momentum of an object?

• Weight and velocity

• Mass and velocity

• Mass and speed

• Weight and speed

In which direction does momentum act?

• Same as velocity

• Perpendicular to velocity

• Opposite to velocity

• Random direction

What happens to an object's momentum if no external force acts on it?

• It becomes zero

• It remains constant

• It increases

• It decreases

How does a baseball bat affect the momentum of a ball?

• It changes the ball's direction

• It increases the ball's mass

• It decreases the ball's velocity

• It stops the ball's momentum

Why is the concept of momentum important in physics?

• It is not applicable to space travel

• It is irrelevant to engineering

• It helps in understanding basic particles

• It is only used in sports
