Question

what is the equation for determining force given the mass and acceleration of an object, newtons 2nd law?

$f = v/t$

$f = ma$

$f = d/t$

$f = va$

Explanation:

Step1: Analyze each option

• \( F = v/t \): This is the formula for acceleration (\( a=\frac{v}{t} \), where \( v \) is velocity change and \( t \) is time), not force.
• \( F = ma \): Newton's second law states that force (\( F \)) is equal to mass (\( m \)) times acceleration (\( a \)).
• \( F = d/t \): This is the formula for average speed (\( v = \frac{d}{t} \), where \( d \) is distance and \( t \) is time), not force.
• \( F = va \): There is no physical meaning for this combination in the context of force - mass - acceleration relations.

Answer:

B. \( F = ma \)
