Ans. Motion is the change in position of an object with respect to a reference point. It can be described in terms of distance, displacement, speed, velocity, and acceleration.

2. What are the different types of motion?

Ans. The different types of motion include linear motion (motion in a straight line), rotational motion (motion around an axis), and oscillatory motion (repeated back and forth motion).

3. What is the difference between speed and velocity?

Ans. Speed is a scalar quantity that measures how fast an object is moving, while velocity is a vector quantity that includes both speed and direction of motion.

4. What is acceleration and how is it calculated?

Ans. Acceleration is the rate of change of velocity over time. It is calculated by dividing the change in velocity by the time taken for the change to occur.

5. How does friction affect motion?

Ans. Friction is a force that opposes motion and can cause objects to slow down or come to a stop. It is dependent on the surfaces in contact and the normal force between them.
