Question

question 3 of 20
which quantities define momentum?
a. mass and velocity
b. mass and acceleration
c. mass and force
d. mass and speed

Explanation:

Step1: Recall the formula for momentum

The formula for momentum is \( p = mv \), where \( p \) is momentum, \( m \) is mass, and \( v \) is velocity.

Step2: Analyze each option

• Option A: Mass and velocity. Since \( p = mv \), this is correct.
• Option B: Mass and acceleration. Acceleration (\( a \)) is not part of the momentum formula.
• Option C: Mass and force. Force (\( F \)) is not part of the momentum formula.
• Option D: Mass and speed. Speed is a scalar, while velocity in momentum formula is a vector.

Answer:

A. Mass and velocity
