Question

question 4 (1 point)
what are some ways to write the second law of motion?
□ a f = m × a
□ b a = f / m
□ c m = f / a
□ d a = m / f

question 5 (1 point)
the heavier the object the easier it is to accelerate.
○ true
○ false

question 6 (1 point)
if the net force on a moving objectg is 0 it will continue to move in a straight line at what speed?
○ a it will stop moving
○ b speed will decrease
○ c same speed
○ d increase speed

Explanation:

Question 4:

Step 1: Newton's second law

Newton's second law is \( F = ma\).

Step 2: Rearranging for \(a\)

If we solve \( F = ma\) for \(a\), we divide both sides by \(m\), getting \(a=\frac{F}{m}\).

Step 3: Rearranging for \(m\)

If we solve \( F = ma\) for \(m\), we divide both sides by \(a\), getting \(m=\frac{F}{a}\).

Question 5:

Step 1: Newton's second law relation

From \(a=\frac{F}{m}\), for a given force \(F\), as \(m\) (mass, related to heaviness) increases, \(a\) (acceleration) decreases. So, heavier objects are harder to accelerate.

Question 6:

Step 1: Newton's first law

Newton's first law (a special case of the second law when \(F = 0\)) states that an object in motion will stay in motion with a constant velocity (same speed and direction) if the net force \(F_{net}=0\).

Answer:

Question 4: A. \( F = m\times a \), B. \( a=\frac{F}{m} \), C. \( m = \frac{F}{a} \)
Question 5: False
Question 6: C. same speed
