Question

4 a 2 kg wagon
_kg·m/s momentum
a 1 b. 2
c. 6 d. 8

1. the amount of matter in an object is

10.
_
mo
a speed b. velocity
c. mass d. momentum

1. if an eagle and a bumble bee are

both flying at 2.78 m/s, which has the
greater momentum?
a eagle b. bumble bee
c. they are equal d. all of these

Explanation:

• Question 5:
• Speed is the rate of change of distance.
• Velocity is the rate of change of displacement (a vector quantity).
• Momentum is mass times velocity.
• Mass is the amount of matter in an object.
• Question 6:
• The formula for momentum is \(p = mv\) (where \(p\) is momentum, \(m\) is mass, and \(v\) is velocity).
• Given that the velocity \(v\) is the same (\(2.78m/s\)) for both the eagle and the bumble - bee.
• An eagle has a much larger mass \(m\) than a bumble - bee.
• Since \(p = mv\) and \(v\) is constant, the object with the larger mass (\(m\)) will have a larger momentum (\(p\)).

Answer:

• Question 5: C. mass
• Question 6: A. eagle
