Question

question 1 (1 point)
what does acceleration directly depend on
a speed only
b net force
c time

question 2 (1 point)
an object will continue to do what it is doing unless acted upon some an unbalanced or not equal in other words force
o true
o false

question 3 (1 point)
there are 2 correct answers. acceleration is zero when... pick two answer choices.
□ a the object is not moving and is at rest
□ b when the object in motion continues with the same velocity and direction
□ c when there is a net force of non - zero
□ d when object changes direction

Explanation:

• Question 1: According to Newton's second law \(F = ma\) (where \(F\) is net force, \(m\) is mass, and \(a\) is acceleration), acceleration \(a=\frac{F}{m}\). So acceleration directly depends on net force.
• Question 2: Newton's first law (law of inertia) states that an object will remain at rest or in uniform - motion in a straight line unless acted upon by an unbalanced force.
• Question 3:
• For an object at rest (\(v = 0\) and \(\Delta v=0\)), using the formula \(a=\frac{\Delta v}{\Delta t}\), \(a = 0\).
• For an object in motion with constant velocity (\(\Delta v = 0\)), using \(a=\frac{\Delta v}{\Delta t}\), \(a = 0\). When there is a non - zero net force, by \(F = ma\), \(a

eq0\). When an object changes direction (even if speed is constant, velocity changes as velocity is a vector), \(a
eq0\).

Answer:

• Question 1: B. Net Force
• Question 2: True
• Question 3: A. the object is not moving and is at rest; B. when the object in motion continues with the same velocity and direction
