What to Focus On
- Motion is change in position with time.
- Rectilinear motion means motion along a straight line.
- A point object is an object whose size is negligible compared with the distance travelled.
- Instantaneous velocity is the rate of change of position with time.
- It is given by v = dx/dt.
- Its graphical meaning is the slope of the tangent on an x-t graph.
- Acceleration is the rate of change of velocity with time.
- Average acceleration is Δv/Δt.
- Instantaneous acceleration is dv/dt.
Common Mistakes to Avoid
Velocity and speed are the same thing.
Average speed and average velocity are always equal.
Average velocity is always the arithmetic mean of initial and final velocities.
Memory Tips
Motion as change in position with time
Kinematics versus dynamics
Point-object approximation
Instantaneous velocity definition
