1st Semester Final Exam Review of MOTION

Front

What type of friction do objects falling through air experience?

Back

Fluid friction.

Front

What causes a balloon to move when air escapes from it?

Back

Action-reaction forces.

Front

If four forces are acting on a box, how can you determine its direction of movement?

Back

By analyzing the net force acting on the box.

Front

What does a positive acceleration indicate about an object's velocity?

Back

The object's velocity is increasing.

Front

What part of a car is responsible for causing negative acceleration?

Back

Brake pedal.

Front

Define terminal velocity.

Back

The constant speed an object reaches when the force of gravity is balanced by the drag force of the fluid it is moving through.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

Explain the concept of action-reaction forces.

Back

For every action, there is an equal and opposite reaction.

Front

What is the significance of a velocity-time graph?

Back

It shows how an object's velocity changes over time.

Front

What happens to the motion of an object when the net force acting on it is zero?

Back

The object remains at rest or continues to move at a constant velocity.
