True or False: If the net force on an object is constant and the mass decreases, then the acceleration increases
True. According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. If the net force remains constant and the mass decreases, the acceleration will increase as there is a smaller mass to oppose the force.
True.
To understand why this is true, let's break it down step by step:
1. Newton's second law of motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Mathematically, this can be expressed as F = ma, where F represents the net force, m represents the mass of the object, and a represents the acceleration.
2. In this scenario, we are told that the net force on the object is constant. This means that F remains the same regardless of any changes in mass or acceleration.
3. According to Newton's second law, a decrease in mass (m) will result in an increase in acceleration (a) if the net force (F) remains constant. Since F = ma, when the mass is decreased, the acceleration must increase in order to keep the equation balanced.
Therefore, if the net force on an object is constant and the mass decreases, the acceleration will increase.
True. According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. Mathematically, the relationship can be expressed as:
acceleration = net force / mass
If the net force on an object remains constant and its mass decreases, the denominator in the equation reduces. As a result, the acceleration increases since the force is divided by a smaller value.
