1D Kinematics

Front

What is 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

Define displacement.

Back

Displacement is the vector quantity that represents the change in position of an object. It is the shortest distance from the initial to the final position, including direction.

Front

What is the formula for calculating average velocity?

Back

Average velocity is calculated using the formula: Average Velocity = Total Displacement / Total Time.

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 the distance traveled if an object moves at a constant speed?

Back

Distance = Speed x Time. For example, if a bird flies at 5 m/s for 60 seconds, the distance traveled is 5 m/s x 60 s = 300 m.

Front

What does a flat line on a distance-time graph indicate?

Back

A flat line on a distance-time graph indicates that the object is at rest, meaning it is not changing its position over time.

Front

What does a steeper slope on a distance-time graph represent?

Back

A steeper slope on a distance-time graph represents a higher speed, indicating that the object is moving faster.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time. It can be positive (increasing speed) or negative (deceleration).

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

If an object moves 10 meters east and then 10 meters west, what is its displacement?

Back

The displacement is 0 meters, as the object returns to its original position.
