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 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 negative velocity indicate?

Back

A negative velocity indicates that an object is moving in the opposite direction to the defined positive direction.

Front

What is the significance of zero acceleration?

Back

Zero acceleration means that an object is either at rest or moving at a constant velocity.

Front

Explain the concept of free fall.

Back

Free fall is the motion of an object under the influence of gravitational force only, with no other forces acting on it.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final velocity - Initial velocity) / Time taken.

Front

What does it mean for an object to have zero displacement?

Back

An object can have zero displacement if it returns to its starting position, regardless of the distance traveled.
