What are the key differences between inertial and non-inertial reference frames?
Inertial: Not accelerating, constant velocity, laws of physics consistent. Non-inertial: Accelerating, laws of physics may appear different.
Compare observed velocity and object velocity.
Object velocity: Actual velocity of the object. Observed velocity: Combination of object velocity and observer's reference frame velocity.
How do you convert measurements between reference frames?
- Determine the relative velocity of the frames. 2. Use vector addition/subtraction to adjust the measurements based on the relative velocity.
How do you determine the observed velocity?
- Identify the object's velocity. 2. Identify the velocity of the observer's frame. 3. Use vector addition or subtraction to combine the velocities.
List the steps to solve relative velocity problems in one dimension.
- Define the positive direction. 2. Assign velocities with correct signs. 3. Add or subtract velocities depending on the direction of motion.
What is the key difference between an inertial and non-inertial reference frame?
Inertial Frame: Not accelerating (constant velocity or at rest). Non-Inertial Frame: Accelerating.
Compare how velocity is perceived in two different inertial reference frames.
Different inertial reference frames: Velocity is different. Acceleration: Acceleration remains the same.
