According to the Force-Velocity Model, what is the direct relationship between the force applied to an object and its change in velocity?

An applied force is inversely proportional to an object's change in velocity.

An applied force is directly proportional to an object's change in velocity.

An applied force has no relationship to an object's change in velocity.

An applied force only affects velocity if the object is already at rest.

A toy car is pushed with the same initial speed across a carpet and then across a smooth wooden floor. On which surface will the car experience a greater deceleration, and why?

The wooden floor, because its smooth surface allows for a more rapid change in velocity.

The carpet, because the higher friction it creates exerts a stronger opposing force on the car.

Both surfaces, because the car's initial speed was the same in both trials.

The wooden floor, because lower friction means the car's velocity must change more quickly to stop.

A surface that applies a strong opposing force, such as coarse sandpaper.

A very smooth surface like ice to allow the ball to stop on its own.

A heavy surface, because the surface's mass will absorb the ball's energy.

A surface with a very low coefficient of friction to prevent the ball from skidding.

The deceleration will be halved.

The deceleration will remain the same.

The deceleration will also double.

The deceleration will become four times greater.

The polished surface applied a strong forward force, keeping the cart moving.

The cart's initial push was too strong for friction to have any effect.

The cart did not have enough mass to create a significant stopping force.

The weak friction force from the slippery surface resulted in a very small deceleration.
