Question

In which situation is the object experiencing unbalanced forces?

Answer 1

B. A car slowing as it reaches a stop light

Explanation:

According to Newton's second law, the net force exerted on an object is equal to the product between its mass and its acceleration:

$F=ma$

where

F is the net force

m is the mass of the object

a is its acceleration

This means that when an object is experiencing unbalanced forces ($F\neq 0$), it must have a non-zero acceleration. Therefore, let's analyze the different options:

A. A box resting on a horizontal floor  --> FALSE. Here the acceleration is zero, so no unbalanced forces.

B. A car slowing as it reaches a stop light  --> TRUE. Since the car is slowing down, its velocity is changing, so the acceleration is non-zero and there are unbalanced forces.

C. A car with its cruise control set to 50 mph  --> FALSE. Here the velocity is constant, so no acceleration and no unbalanced forces.

D. A rocket sitting on the launch pad --> FALSE. Here the rocket is stationary, so no acceleration, and no unbalanced forces.
