Acceleration is a vector representing the change in velocity with respect to change in time.
We can further explore this concept through the example of uniform circular motion.
When the object is at 12-o’clock and going to the right, there is a downward push to bring it to the 3 o’clock position. When the object is at 3-o’clock and going to the right, there is a push to the left to bring it to the 6 o’clock position.
- Acceleration is change is velocity over a period of time.
- The acceleration of uniform circular motion always points towards the center.
- Uniform circular motion: movement of an object along the circumference of a circle with constant speed and changing direction.
