Question

question 3 (2 points)
consider newtons 2nd law. if we assume a constant force, but we double the mass,
what happens to acceleration as a result?
it doubles
it will be cut in half
it triples
it will decrease by 1/3
question 4 (2 points)

Explanation:

Step1: Write Newton's second law formula

Newton's second law is \(F = ma\), where \(F\) is force, \(m\) is mass, and \(a\) is acceleration. We can express acceleration as \(a=\frac{F}{m}\).

Step2: Analyze the change when mass is doubled

Let the initial mass be \(m_1 = m\) and the initial acceleration be \(a_1=\frac{F}{m}\). When the mass is doubled, \(m_2 = 2m\). Then the new acceleration \(a_2=\frac{F}{m_2}\). Substitute \(m_2 = 2m\) into the formula, we get \(a_2=\frac{F}{2m}\). Since \(a_1=\frac{F}{m}\), we can see that \(a_2=\frac{1}{2}a_1\).

Answer:

it will be cut in half
