Study Notes
Distance vs Displacement
- Distance is the total length of the path traveled by an object.
- Displacement is the change in position of an object from its initial point to its final point. It is a vector quantity, meaning it has both magnitude and direction.
Average Velocity
- Average velocity is the rate of change of displacement over time.
- Mathematical definition: Average velocity = (Final displacement - Initial displacement) / Total time.
Position-Time Graph
- The slope of a position-time graph represents the velocity of the object.
- A steeper slope indicates a higher velocity.
- A negative slope indicates that the object is moving in the opposite direction of the positive direction.
Matching Terms
- Speed is the rate at which an object covers distance. It is a scalar quantity, meaning it only has magnitude.
- Average speed is the total distance traveled divided by the total time taken.
- Instantaneous velocity is the velocity of an object at a particular instant in time.
- Acceleration is the rate of change of velocity.
Calculating Average Velocity
- The total distance traveled from point A (30m) to point F (-53m) is 83 meters.
- The average velocity of the car is -1.66 m/s.
- This is calculated by dividing the total displacement (-83m) by the total time (50 seconds).
Additional Information
- Speed is always greater than or equal to average velocity. This is because speed considers the total distance traveled, while average velocity considers only the displacement.
- If the acceleration is negative, the velocity will decrease.
- The initial position of a particle with position equation x = 2 + 3t - 4t^2 is 2 meters when t=0.
- An object moving in uniform velocity has zero acceleration.
- The formula for calculating average speed is: Average speed = Total distance traveled / Total time taken.
