Understanding Linear Momentum

What two factors are necessary for an object to have momentum?

• Force and distance

• Velocity and time

• Mass and velocity

• Mass and acceleration

What is the symbol used for momentum in physics equations?

• F

• M

• V

• P

What is the unit of momentum in the metric system?

• Kilogram meter per second

• Meter per second squared

• Newton

• Joule

Which of the following is true about momentum?

• It is measured in Joules.

• It is independent of direction.

• It is a vector quantity.

• It is a scalar quantity.

What principle states that momentum is conserved in a closed system?

• Conservation of charge

• Conservation of energy

• Conservation of mass

• Conservation of momentum

In the example with the bowling ball, what was its momentum if it had a mass of 6 kg and a velocity of 2.5 m/s?

• 20 kg m/s

• 18 kg m/s

• 15 kg m/s

• 12 kg m/s

Which object had more momentum: the cannonball or Usain Bolt?

• Cannonball

• Usain Bolt

• Both had the same momentum

• It cannot be determined

What was the mass of the cannonball used in the comparison with Usain Bolt?

• 6 kg

• 94 kg

• 250 kg

• 5.5 kg

To match the momentum of the cannonball, what speed would Usain Bolt need to achieve?

• 10.44 m/s

• 12.5 m/s

• 14.62 m/s

• 9.58 m/s

How long would it take Usain Bolt to complete the 100-meter dash at the required speed to match the cannonball's momentum?

• 10.44 seconds

• 9.58 seconds

• 8.5 seconds

• 6.84 seconds
