Newton's second law states that if an object has zero acceleration, the net force acting on it is zero.
My question is if you have an object at constant acceleration moving downward is there a net force being applied to it?
Does constant acceleration= zero net force?
Yes, for course. Remember that acceleration is a vector, so net force= mass *acceleration. If acceleration is not zero, force is not zero.
an object is accelerating at 2 ft/s^2. if the net fore is tripled and the mass is doubled, then what is the new acceleration
In the case of an object moving downward with constant acceleration, there is indeed a net force being applied to it. According to Newton's second law, the net force acting on an object is equal to the mass of the object multiplied by its acceleration. Since the acceleration is not zero in this scenario, the net force is also not zero.
To find the net force, you need to know the mass of the object and its acceleration. Once you have those values, you can multiply them together to calculate the net force. It's important to remember that force and acceleration are both vector quantities, meaning they have both magnitude and direction. So, when calculating the net force, you must consider the direction of the acceleration as well.
Therefore, in the case of an object at constant acceleration moving downward, there is a net force acting on it. The net force will be equal to the mass of the object multiplied by the magnitude of the acceleration, taking into account its direction.
