Chapter 2 Flashcard - Linear Motion

Front

What is the formula to calculate the final velocity of an object under constant acceleration?

Back

Final Velocity (v) = Initial Velocity (u) + (Acceleration (a) × Time (t))

Front

Define acceleration due to gravity.

Back

Acceleration due to gravity is the acceleration experienced by an object due to the gravitational force of the Earth, approximately 9.81 m/s² (often rounded to 10 m/s² for simplicity in calculations).

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

How do you calculate average speed?

Back

Average Speed = Total Distance / Total Time.

Front

What does a negative acceleration indicate about an object's motion?

Back

Negative acceleration indicates that the object is slowing down or decelerating.

Front

What is the significance of the vertex in a velocity-time graph?

Back

The vertex indicates a change in the direction of motion, such as a change from positive to negative velocity.

Front

How can you determine the total time an object is in the air when thrown vertically?

Back

Total Time = 2 × (Initial Velocity / Acceleration due to gravity).

Front

What is the effect of air resistance on an object in free fall?

Back

Air resistance opposes the motion of the object, reducing its acceleration and terminal velocity.

Front

What does a flat line on a velocity-time graph represent?

Back

A flat line indicates constant velocity, meaning the object is moving at a steady speed without acceleration.

Front

How do you find the distance traveled using a velocity-time graph?

Back

The distance traveled is equal to the area under the velocity-time graph.
