1D KINEMATICS REVIEW

Front

What is the definition of 1D Kinematics?

Back

1D Kinematics is the branch of mechanics that deals with the motion of objects along a straight line, focusing on concepts such as displacement, velocity, acceleration, and time.

Front

What does a Position-Time (PT) graph represent?

Back

A Position-Time graph shows how the position of an object changes over time, indicating whether the object is moving forward, backward, or at rest.

Front

What does a Velocity-Time (VT) graph indicate?

Back

A Velocity-Time graph illustrates how the velocity of an object changes over time, helping to identify periods of acceleration, deceleration, and constant velocity.

Front

What is the formula for calculating average speed?

Back

Average speed = Total distance traveled / Total time taken.

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravity alone, with no other forces acting on it.

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately -9.8 m/s².

Front

How do you determine if an object is at rest using a PT graph?

Back

An object is at rest if the PT graph is a horizontal line, indicating that the position does not change over time.

Front

What does a negative slope on a PT graph indicate?

Back

A negative slope on a PT graph indicates that the object is moving backward.

Front

If an object is moving with constant velocity, what does its VT graph look like?

Back

A VT graph of an object moving with constant velocity is a horizontal line above or below the time axis, indicating a steady speed.

Front

What is the significance of the area under a VT graph?

Back

The area under a VT graph represents the displacement of the object over the time interval.
