Momentum and Its Calculation

The video tutorial discusses the concept of momentum, explaining how it is calculated using the formula: momentum equals mass times velocity. The teacher emphasizes the importance of understanding the units involved, such as kilograms for mass and meters per second for velocity. The tutorial provides examples to illustrate how momentum varies with changes in mass and velocity, using scenarios like carts and bowling balls. The teacher also encourages students to ask questions and engage with the material.

What is the formula for calculating momentum?

• Mass divided by velocity

• Mass times velocity

• Velocity divided by mass

• Mass plus velocity

What is the unit of momentum?

• Meters times kilograms per second

• Kilograms times meters per second

• Meters per second

• Kilograms per second

If two objects have the same velocity, which one will have more momentum?

• The one with more speed

• They will have the same momentum

• The one with more mass

• The one with less mass

What happens to momentum if mass is doubled while velocity remains constant?

• Momentum is halved

• Momentum remains the same

• Momentum is doubled

• Momentum is quadrupled

How does speed affect the momentum of objects with the same mass?

• Higher speed results in less momentum

• Higher speed results in more momentum

• Speed does not affect momentum

• Momentum is only affected by mass

If two objects have the same mass but different velocities, which has more momentum?

• The one with more mass

• They have the same momentum

• The one with more velocity

• The one with less velocity

A 30 kg cart moving at 10 m/s has what momentum?

• 3 kg m/s

• 3000 kg m/s

• 300 kg m/s

• 30 kg m/s

In a football analogy, which player has more momentum?

• The player with the faster 40-yard dash

• A heavier player running at the same speed

• A lighter player running at the same speed

• Both have the same momentum

What is the momentum of a 2 kg bowling ball moving at 50 m/s?

• 50 kg m/s

• 25 kg m/s

• 100 kg m/s

• 200 kg m/s

How can you calculate velocity if you know momentum and mass?

• Multiply momentum by mass

• Subtract mass from momentum

• Divide momentum by mass

• Add momentum and mass
