If the racetrack’s height is increased, then the car will move faster because raising the start height increases its gravitational potential energy (mgh), which converts to kinetic energy (½mv²) as the car goes down, so a higher height gives a larger v (v ≈ √(2gh)) assuming friction and air resistance stay the same.
How can motion be described?
- By position (where the object is) and how it changes with time.
- By speed (how fast it moves) and velocity (speed with direction).
- By acceleration (how velocity changes).
- With numbers and units (e.g., meters, seconds, m/s for speed) and with graphs (position vs. time, speed vs. time).
