Which of the following would have more momentum: A 100 g man running at 15 m/s or a 100 kg man running at 4 m/s?

• Man running at 15 m/s

• Man running at 4 m/s

What is the relationship between velocity and momentum?

• As the velocity increases, the momentum decreases

• As the velocity decreases, the momentum increases

• As the velocity increases, the momentum increases

• As the velocity decreases, the momentum does not change

____________ Is a type of collison in which the total kinetic energy of the objects before and after the collison is equal

• Elastic Energy

• Inelastic Energy

• Car crash

• Momentum Collison

During inelastic Collison, kinetic energy can be lost. Which of the following is an example of what the kinetic energy is lost to?

• Sound energy

• Thermal energy

• Deformation of the objects involved

• All of the above

What are the units for momentum (p)?

• kg/s

• m/s

• N

• kg*m/s

A bowling ball, wrecking ball, and ping pong ball are all rolled down a hill. Which of the following is an example of what kinetic energy is lost to?

• Bowling Ball

• Wrecking Ball

• Ping Pong Ball

• They will have the same momentum

A soccer ball has a momentum of 3,000 kg*m/s. What would be the momentum of the soccer ball if the mass of the ball were to double?

• 3,000 kg*m/s

• 1,500 kg*m/s

• 6,000 kg*m/s

• The ball would have no momentum

What is the momentum (p) of a football player with a mass of 150 kg and a velocity of 4 m/s? Equation: p = m * v

• 150 kg*m/s

• 600 kg*m/s

• 37.5 kg*m/s

• 0 kg*m/s
