Key Topics to Revise
Basic Concepts of Motion
- Motion is the change in position of an object with respect to time
- An object is considered a point object when its size is much smaller than the distance it travels
- Position is specified with reference to a chosen origin - positive to the right, negative to the left
Velocity and Speed
- Speed is distance traveled per unit time (scalar quantity)
- Velocity is displacement per unit time (vector quantity)
- Average velocity can be zero even when average speed is not zero
Acceleration
- Acceleration is the rate of change of velocity with respect to time
- Can result from change in speed, direction, or both
- Can be positive, negative, or zero
Kinematic Equations of Motion
- These equations apply only to uniformly accelerated motion
- Connect five quantities: initial velocity (v₀), final velocity (v), acceleration (a), time (t), and displacement (x)
- Any three known quantities can be used to find the other two
