which does NOT change when an unbalanced force acts on an abject?
a) displacement
b) velocity
c) mass
d) motion
mass
Mass
When an unbalanced force acts on an object, there are certain properties that can change. In order to determine which of the given options does not change when an unbalanced force acts on an object, let's examine each one.
a) Displacement: Displacement refers to the change in position of an object. When an unbalanced force acts on an object, its displacement may indeed change. For example, if you push a box across the floor, the displacement of the box will change.
b) Velocity: Velocity is the rate at which an object's position changes. An unbalanced force can definitely affect an object's velocity. For instance, if you push a car, the car's velocity will change.
c) Mass: Mass is a measure of the amount of matter in an object. An unbalanced force does not directly change an object's mass. The mass remains the same regardless of external forces acting upon it.
d) Motion: Motion refers to the state of an object being in movement or at rest. When an unbalanced force acts on an object, it can cause a change in motion. For instance, if you push a ball, it may start moving or change its direction of motion.
Therefore, the property that does not change when an unbalanced force acts on an object is c) mass.
