The correct response is:
If the forces on an object became unbalanced.
Unbalanced forces result in a net force that changes the object's velocity, which can result in acceleration (speeding up, slowing down, or changing direction).

The correct response is:
If the forces on an object became unbalanced.
Unbalanced forces result in a net force that changes the object's velocity, which can result in acceleration (speeding up, slowing down, or changing direction).
The expected shape of the graph of acceleration versus force for a model rocket (given that acceleration is directly proportional to force according to Newton's second law, \( F = ma \)) would be:
a sloped line, where the slope is 1/mass.
In this relationship, acceleration (a) is plotted on the y-axis and force (F) on the x-axis, the slope of the line represents \(\frac{1}{m}\) (where m is mass), signifying that as force increases, acceleration increases proportionally.
The correct response based on the relationship defined by Newton's second law (\(F = ma\)) is:
As mass increases, the acceleration decreases, because mass and acceleration are inversely proportional.
When a constant net force is applied, increasing mass leads to a decrease in acceleration, reflecting the inverse relationship between mass and acceleration.
The correct response is:
the magnitude of the force in Newtons and the direction.
To determine if forces are balanced, you need to know both the magnitude and the direction of each force acting on the object. Balanced forces occur when the net force equals zero, which happens when the forces are equal in magnitude and opposite in direction.
