Frictional force triples

It halves

It reduces to a third

It has no change

No adjustment is needed as velocity will remain constant without any external forces applied.

Halve net external force because there is more inertia resistance due to additional mass.

Double net external force to compensate for increased inertia resistance due to added mass.

Reduce net external force slightly below double because some energy goes into overcoming inertia resistance with extra mass present now too.

The object continues moving at a constant velocity or remains at rest.

The object immediately comes to rest regardless of previous motion.

There is uniform acceleration in the direction of applied forces.

There will be increasing acceleration in the opposite direction of applied forces

It decreases since heavier objects resist changes in motion more than lighter ones.

It doubles since doubling the mass doubles the acceleration in F=ma relationship.

It increases because more massive objects have higher accelerations for given forces.

It will not change because acceleration due to gravity depends on radius but not mass.

There is no effect unless gravity acts on it as well.

It causes uniform circular motion around a fixed point.

It increases only the speed of the object without changing direction.

It increases the object's velocity at an increasing rate.

None of these must be true.

The object's direction of motion can change, but not its speed.

The object is not moving.

The object is speeding up.

Mass equals force divided by acceleration.

Force equals mass times acceleration.

Acceleration equals force divided by mass.

Force is inversely proportional to the product of mass and acceleration.

It quadruples.

It doubles.

It remains the same.

It halves.
