Kinematics

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

Define displacement.

Back

Displacement is the vector quantity that represents the change in position of an object, measured from the initial position to the final position.

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 acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What is the formula for calculating average velocity?

Back

Average velocity = (Final position - Initial position) / (Time interval).

Front

What does a flat line on an x-t graph indicate?

Back

A flat line on an x-t graph indicates that the object is at rest, as there is no change in position over time.

Front

What does a steeper slope on an x-t graph represent?

Back

A steeper slope on an x-t graph represents a higher speed of the object.

Front

What happens to the velocity of an object thrown upward at its highest point?

Back

At the highest point, the velocity of the object is zero.

Front

What is the acceleration of an object in free fall?

Back

The acceleration of an object in free fall near the Earth's surface is approximately 9.81 m/s² downward.

Front

How do you calculate the final velocity of an object under constant acceleration?

Back

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