You see an object accelerate towards the left. Which of the following statements is correct?
A. There is a net force on the object upwards.
B. There is a net force on the object to the left.
C. There is a net force on the object to the right.
D. There is a net force on the object downwards.
If it accelerates to the left, there is a force pulling (or pushing) it to the left. That force if pulling the object, would be on the right, if it is pushing, it would be on the left. Accelerations are in the same direction as the net force.
The answer is B, because if there is a force going against the object and it moves left then it has a net force on the object to the left
To determine the correct statement, let's review the relationship between force and acceleration. According to Newton's second law of motion, the net force acting on an object is directly proportional to its acceleration and is in the same direction. This can be expressed by the equation F=ma, where F is the net force, m is the mass of the object, and a is the acceleration.
In this scenario, the object is accelerating towards the left. Since acceleration and net force have the same direction, the net force on the object must also be towards the left. Therefore, the correct statement is:
B. There is a net force on the object to the left.
