Knowledge
Motion is defined as the change in position of an object concerning time. This chapter discusses various aspects of motion, focusing on concepts like velocity, acceleration, and kinematic equations for uniformly accelerated motion. The relationships between these concepts are explored through practical examples and theoretical explanations, culminating in an understanding of relative velocity.

What we have learnt
- Motion is described as a change in position over time and can be quantified using velocity and acceleration.
- Instantaneous velocity is defined as the limit of average velocity as the time interval approaches zero.
- Kinematic equations relate displacement, time, initial velocity, final velocity, and acceleration for uniformly accelerated motion.
Key Concepts
-
Term: Motion
Definition: The change in position of an object concerning time.
-
Term: Velocity
Definition: The rate of change of position, defined as the change in displacement over time.
-
Term: Acceleration
Definition: The rate of change of velocity with respect to time.
-
Term: Instantaneous Velocity
Definition: Velocity of an object at a specific instant, calculated as the limit of average velocity as the time interval approaches zero.
-
Term: Kinematic Equations
Definition: Equations that describe the motion of objects under uniform acceleration, relating displacement, initial and final velocity, acceleration, and time.
