Question

If you apply an unbalanced force to this object it will ______. Mention all that will apply: change velocity, accelerate, change position

Answer 1

Answer:

All of them: change velocity, accelerate, change position

Explanation:

We can answer this question by using Newton's second law:

F = ma

where

F is the net force on the object

m is the mass of the object

a is the acceleration

We notice that when there is an unbalanced force on the object, $F\neq 0$, and therefore

$a\neq 0$

whcih means that the object will accelerate.

But acceleration is the rate of change of velocity, v:

$a=\frac{\Delta v}{\Delta t}$

And so,

$\Delta v \neq 0$

which means that the object will change velocity.

If the object is changing velocity, this means that it is also moving: therefore, the position of the object must be changing, so also the option "change position" is correct.
