Question

question 11 (1 point)
what is the unit used for momentum?

a p

b kg*m/s

c m/s

d m/s2

question 12 (1 point)
in the equation p = m x x, what does p represent?

a inertia

b momentum

c position

d friction

Explanation:

• For Question 11: Momentum is defined as the product of mass and velocity. Mass has SI - unit kg and velocity has SI - unit m/s. So, the unit of momentum is kg*m/s.
• For Question 12: The common formula for momentum is \(P = M\times V\) (where \(M\) is mass and \(V\) is velocity), so \(P\) represents momentum.

Answer:

Question 11: B. kg*m/s
Question 12: B. momentum
