Question

During an experiment in which you are investigating the acceleration changes due to force changes, what value must stay constant during these trials?
Force
Mass
Velocity
Acceleration

Answer 1

In an experiment investigating acceleration changes due to force changes, the value that must stay constant during the trials is **mass**. According to Newton's second law of motion (F = ma), if you are changing the applied force (F) and observing changes in acceleration (a), you must keep the mass (m) constant to study the relationship between force and acceleration accurately. Therefore, by varying the force while keeping the mass unchanged, you can observe how acceleration changes in response.
