Constant acceleration refers to motion where the velocity changes at a steady rate. This means the acceleration remains constant over time. Understanding constant acceleration is crucial for solving many physics problems, especially those involving projectiles and moving objects. Key equations include those relating displacement, initial velocity, final velocity, acceleration, and time. These equations allow us to predict and analyze the motion of objects under constant acceleration.
When solving constant acceleration problems, it's essential to identify the known variables and the unknown variable you need to find. Choose the appropriate equation that relates these variables, and then solve for the unknown. Always pay attention to units and directions! Let's practice!
Match the term with its correct definition:
| Term | Definition |
|---|---|
| 1. Acceleration | A. The rate of change of position. |
| 2. Velocity | B. The change in velocity over time. |
| 3. Displacement | C. The final speed of an object. |
| 4. Initial Velocity | D. The starting speed of an object. |
| 5. Final Velocity | E. The change in position of an object. |
