Question

multiple - choice question
what is the equation from the second law?
$f = ma$
$s = d/t$
$pe = mgh$

Explanation:

Step1: Recall Newton's second law

Newton's second law of motion states that the force \(F\) acting on an object is equal to the mass \(m\) of the object multiplied by its acceleration \(a\).

Step2: Analyze each option

• For \(F = ma\), this is the formula from Newton's second law.
• \(s=\frac{d}{t}\) is the formula for speed (where \(s\) is speed, \(d\) is distance, \(t\) is time), not related to Newton's second law.
• \(PE=mgh\) is the formula for gravitational potential energy (where \(PE\) is potential energy, \(m\) is mass, \(g\) is acceleration due to gravity, \(h\) is height), not related to Newton's second law.

Answer:

\(F = ma\)
