1. Identify velocity, distance, and time
- Velocity (v): The speed of an object in a given direction.
- Distance (d): The total length of the path traveled by an object.
- Time (t): The duration over which the motion occurs.
2. Solving for velocity
- Use the formula: v = d / t
- Example: If an object travels 100 meters in 20 seconds, its velocity is 5 m/s.
3. Solving for distance
- Use the formula: d = v × t
- Example: If an object moves at 10 m/s for 5 seconds, it covers 50 meters.
4. Solving for time
- Use the formula: t = d / v
- Example: If an object travels 60 meters at 12 m/s, it takes 5 seconds.
5. Acceleration due to gravity
- On Earth, acceleration due to gravity (g) is approximately 9.8 m/s².
- This means that every second, the velocity of a falling object increases by 9.8 m/s.
6. Free fall equations
- Final velocity: v = g × t
- Distance fallen: d = (1/2) × g × t²
- Example: After 3 seconds of free fall, velocity is 29.4 m/s and distance fallen is 44.1 meters.
