What is position?
Where an object is located, measured in meters (m).
What is velocity?
How fast an object is moving and in what direction, measured in meters per second (m/s).
What is acceleration?
How much an object's velocity is changing over time, measured in meters per second squared (m/s²).
What is free fall?
When an object falls under the influence of gravity alone.
Define a scalar quantity.
A quantity with magnitude only.
Define a vector quantity.
A quantity with both magnitude and direction.
What are the steps to analyze 2D motion?
- Break the motion into x and y components. 2. Analyze x and y components separately. 3. Time is the same for both x and y.
What are the steps to solve projectile motion problems?
- Identify initial velocity and launch angle. 2. Calculate initial x and y components of velocity. 3. Analyze vertical motion using kinematic equations with a = -g. 4. Analyze horizontal motion with constant velocity. 5. Use time to connect x and y components.
What are the steps to find the resultant vector?
- Break down vectors into their x and y components using trigonometry (sin and cos). 2. Combine vector components. 3. Find the overall vector using Pythagorean theorem and trigonometry.
