Kinematics Equations & Freefall Review

Front

What is Kinematics?

Back

Kinematics is the branch of physics that describes the motion of objects without considering the forces that cause the motion.

Front

What is the formula for calculating displacement?

Back

Displacement = Final Position - Initial Position.

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

What does freefall mean?

Back

Freefall is the motion of an object under the influence of gravity only, with no other forces acting on it.

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed that a freely falling object eventually reaches when the resistance of the medium prevents further acceleration.

Front

How does air resistance affect falling objects?

Back

Air resistance opposes the motion of falling objects, causing them to fall slower than they would in a vacuum.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the formula for calculating average speed?

Back

Average Speed = Total Distance / Total Time.

Front

What is the significance of the slope in a distance-time graph?

Back

The slope of a distance-time graph represents the speed of the object.

Front

What happens to the velocity of an object in freefall?

Back

The velocity of an object in freefall increases due to the acceleration caused by gravity, approximately 9.81 m/s².
